Answer:PHYSICALLY- sand is spherical in shape with large particles up to 0.18g

Silt also contains more of spherical particles with weights around 0.0029g.

Clay contain plate like particles,which are flat or layered. It's particles are generally lower that silt and sand below 0.0029g.

BEHAVIORS Sand particles are coarse and very porous,water can easily penetrate with no particles cohesion,does not retain water, difficult to expand,it is IDEAL FOR BUILDINGS.

Silt particles are also porous with some coarseness and no particles cohesion. retains water and can expand. NOT IDEAL FOR BUILDINGS.

Clay contain particles that are not coarse,they have high cohesiveness,they are not porous as it is difficult for water to penetrate. NOT IDEAL FOR BUILDINGS.

Explanation: Sand particles are coarse,very porous,contains spherical particles with large particles sizes and IDEAL FOR BUILDINGS

Silt particles are also porous, with some coarseness and with little or no particles cohesion, NOT IDEAL FOR BUILDINGS.

Clay soils are not porous water can not easily flow thought it,it is hard when dry and soft when wet. IT IS NOT A GOOD OPTION FOR BUILDINGS.

What is the critical path and time duration?
kvasek [131]

The critical path is A-B-C, with a duration of 15 minutes.

<u>Explanation</u>:

  • The critical path is A-B-C, with a term of 15 minutes. You don't need to be knowledgeable in computer lingo to make sense of this one (as I made sense of it absent a lot of data on that half of the condition). Here's the manner by which I made sense of this.  
  • The main thing I saw was that "predecessor" was utilized, which implies something precedes the other thing. That provided me the primary insight that A precedes B and C, and that B must precede C. Then, I just included the term times for the three ways, which allowed me 15 minutes.

lakkis [162]

Answer:

Explanation:

Let us Begin with the first Policy;

Email Policy

  • Outline/Overview - At present, email is truly outstanding, simple, and well known correspondence medium which interfaces workers, clients, and different partners of the organization.

Henceforth, it is significant for all representatives to comprehend the best possible utilization of email.

  • Reason/Purpose - The motivation behind the email strategy is to affirm the correct utilization of email address of the organization by the representatives.

  • Scope - The arrangement is covering the utilization of any email which is sent from an organization email address. It additionally applies to all related representatives, clients, and different partners who are working in the interest of the organization.

  • Policy

  1. The email address of the organization ought to be utilized by workers just for business reason. Representatives are restricted to unlawfully utilize the organization email address.
  2. The utilization of the email office must be steady with other security approaches of the organization. It gives the guarantee of the moral conduct inside the organization.
  3. The "Information Protection Standards" must be utilized to make sure about the substance of the messages.
  4. The organization must need to hold just clear email and keep up a record which stores the substance of the necessary messages.
  5. The representatives ought to need to take care during opening any sort of dubious email which originates from unlawful location. They should need to answer to the security chief on the off chance that they got any sort of such email.
  6. It isn't permitted to advance email to any outsider utilizing the organization email address.
  7. The representatives are not permitted to utilize the organization email address for individual works and correspondence.

  • Policy Compliance - The security group of the organization will confirm the consistence of the approach utilizing suitable strategies, for example, stroll through, inward and outside reviews, business instrument reports, video checking, and input. The security group must need to educate and support any sort of special case to the arrangement ahead of time.

  • Related Standards, Policies, and Processes - Data assurance guidelines
  • Definitions and Terms - None

The Second Policy;

WIFI and Internet usage policy

  • Overview -  The expanding utilization of web associations is bringing different sorts of security dangers for the organization. It turns into a significant asset of assault. A WIFI and Internet utilization strategy will control the unlawful and dishonest use of web assets inside the organization.

  • Purpose - The motivation behind WIFI and Internet use strategy is to affirm the best possible utilization of WIFI and Internet by the representatives inside the organization.

  • Scope - The arrangement applies to each web client including full-time representatives, low maintenance workers, colleagues, and so on of the organization.

A pump of a water distribution system at 25°C is powered by a 15 kW electric motor whose efficiency is 90 percent. The water flo
IRISSAK [1]

The friction loss in the system is 3.480 kilowatts.

<h2>Procedure - Friction loss through a pump</h2><h2 /><h3>Pump model</h3><h3 />

Let suppose that the pump within a distribution system is an open system at steady state, whose mass and energy balances are shown below:

<h3>Mass balance</h3>

\dot m_{in}-\dot m_{out} = 0 (1)

\dot m_{in} = \frac{\dot V_{in}}{\nu_{in}} (2)

\dot m_{out} = \frac{\dot V_{out}}{\nu_{out}} (3)

<h3>Energy balance</h3>

\eta \cdot \dot W_{el} + \dot m_{in}\cdot (h_{in}-h_{out}) - \dot W_{f} = 0 (4)

Where:

  • \dot m_{in} - Inlet mass flow, in kilograms per second.
  • \dot m_{out} - Outlet mass flow, in kilograms per second.
  • \dot V_{in} - Inlet volume flow, in cubic meters per second.
  • \dot V_{out} - Outlet volume flow, in cubic meters per second.
  • \nu_{in} - Inlet specific volume, in cubic meters per kilogram.
  • \nu_{out} - Outlet specific volume, in cubic meters per kilogram.
  • \eta - Pump efficiency, no unit.
  • \dot W_{el} - Electric motor power, in kilowatts.
  • h_{in} - Inlet specific enthalpy, in kilojoules per kilogram.
  • h_{out} - Outlet specific enthalpy, in kilojoules per kilogram.
  • \dot W - Work losses due to friction, in kilowatts.

<h3>Data from steam tables</h3>

From steam tables we get the following water properties at inlet and outlet:

Inlet

p = 100\,kPa, T = 25\,^{\circ}C, \nu = 0.001003\,\frac{kJ}{kg}, h = 104.927\,\frac{kJ}{kg}, Subcooled liquid

Outlet

p = 300\,kPa, T = 25\,^{\circ}C, \nu = 0.001003\,\frac{kJ}{kg}, h = 105.128\,\frac{kJ}{kg}, Subcooled liquid

<h3>Calculation of the friction loss in the system</h3>

If we know that \dot V_{in} = 0.05\,\frac{m^{3}}{s}, \nu_{in} = 0.001003\,\frac{m^{3}}{kg}, h_{in} = 104.927\,\frac{kJ}{kg}, h_{out} = 105.128\,\frac{kJ}{kg}, \eta = 0.90 and \dot W_{el} = 15\,kW, then the friction loss in the system is:

\dot W_{f} = \frac{\dot V_{in}}{\nu_{in}}\cdot (h_{in} - h_{out}) + \eta \cdot \dot W_{el}

\dot W_{f} = \left(\frac{0.05\,\frac{m^{3}}{s} }{0.001003\,\frac{m^{3}}{kg} } \right)\cdot \left(104.927\,\frac{kJ}{kg}-105.128\,\frac{kJ}{kg}\right) + (0.90)\cdot (15\,kW)

\dot W_{f} = 3.480\,kW

The friction loss in the system is 3.480 kilowatts. \blacksquare
