Determine the maximum volume in gallons​ [gal] of olive oil that can be stored in a closed cylindrical silo with a diameter of 3

feet​ [ft] so the total pressure at the bottom of the container will not exceed 26 pound-force per square inch​ [psi]. Assume the height of the tank is sufficient to store the amount of olive oil​required, and the surface pressure is 1 atmosphere​ [atm]. The specific gravity of olive oil is 0.86

Answer:

V=1601gal

Explanation:

Hello! This problem is solved as follows,

First we must raise the equation that defines the pressure at the bottom of the tank with the purpose of finding the height that olive oil reaches.

This is given as the sum due to the atmospheric pressure (1atm = 101.325kPa), and the pressure due to the weight of the olive oil, taking into account the above, the following equation is inferred.

P=Poil+Patm

P=total pressure or absolute pressure=26psi=179213.28Pa

Patm= the atmospheric pressure =101325Pa

Poil=pressure due to the weight of olive oil=0.86αgh

α=density of water=1000kg/m^3

g=gravity=9.81m/s^2

h= height that olive oil reaches

solving

P=Poil+Patm

P=Patm+0.86αgh

h=\frac{P-Patm}{0.86\alpha g } =\frac{179214.28-101325}{(0.86)(1000)(9.81)} \\h=9.23m[/tex]

Now we can use the equation that defines the volume of a cylinder.

V=V=\frac{\pi }{4} D^{2} h

D=3ft=0.9144m

h=9.23m

solving

V=\frac{\pi }{4} (0.9144)^{2} 9.23=6.06m^3

finally we use conversion factors to find the volume in gallons

V=6.06m^3\frac{1000L}{1m^3} \frac{1gal}{3.785L} =1601gal

A wheel spins at a constant angular speed of 24rad/s.How many revolutions will the dosk go through in 5minutes?​
Margaret [11]

<u>Answer:</u>

The wheel will go through 1146 revolutions in 5 minutes.

<u>Explanation:</u>

We can the formula:

\boxed{\omega = \frac{2 \pi}{T}}

where

ω ⇒ angular speed (24 rad/s),

T ⇒ time period (? s),

and solve for T to find the time it takes for the wheel to complete one revolution.

⇒  24 = \frac{2 \pi}{T}

⇒  T = \bf \frac{2 \pi}{24}  s

This means it takes \bf \frac{2 \pi}{24} seconds for the wheel to complete one revolution.

Now, using the unitary method,

In \frac{2 \pi}{24} seconds          ⇒    1 revolution completed

In 1 second              ⇒    1 ÷ \frac{2 \pi}{24}   =  \frac{24}{2 \pi}  revolutions completed

In (5 × 60 = ) 300s  ⇒     \frac{24}{2 \pi}   ×  300   = 1145.9

                                                            ≅ 1146 revolutions completed

What are the basic types of heat exchangers?
liraira [26]

Answer:

The two large divisions of heat exchangers are direct contact between fluids and indirect contact between fluids.

Explanation:

A heat exchanger is one of the most used equipment at the level of thermal installations, both at the building, tertiary and industrial levels. A heat exchanger is a device designed to transfer heat between two fluids. These two fluids (liquids, gases) can be in contact or separated by a solid barrier. Its use is basic in all types of air conditioning or refrigeration, air conditioning, energy transfer or chemical processes. Heat transmission occurs through convection and conduction.

Classifying heat exchange systems can be carried out using many different criteria. When classifying different types of heat exchangers, different criteria can be taken into account. Taking into account the degree of contact between the fluids, they are grouped into two different types:

Direct Contact Heat Exchanger:

In direct contact exchangers, heat transfer occurs through a physical mixture of the fluids involved in the process. An example of this type of exchangers are the cooling towers. In this case, direct contact occurs between a stream of hot water (fluid to be cooled) using dry and colder air.

Indirect Contact Heat Exchanger :

In a direct type exchanger there is no direct contact between the fluids and they never mix. The fluids are separated by a solid barrier and may also not coincide at the same time.

Indirect contact heat exchangers can be of various types, being the most used, according to their constructive typology:

  • Concentric tubes or double tube .
  • Shell and tubes .
  • Of plates .
  • Compact heat exchangers .
  • Regenerators .

The concentric tube equipments are the simplest that exist since they are composed of two concentric tubes of different diameter so that one of the fluids circulates inside the smaller one and the other does it through the annular space between both tubes.

Shell and tube exchangers are widely used at an industrial level and use a housing with a multitude of tubes inside.

The equipment of plates are formed by a succession of sheets of metal, armed in a frame and separated by joints, which are fixed with a steel shell. The fluid circulates between these sheets.

When hermetic refrigerant motor-compressors are designed to operate continuously at currents greater than 156 percent of the rat
ANEK [815]

The nameplate of a hermetic refrigerant motor-compressor that is designed to operate continuously at currents greater than 156% of the rated-load current is marked with branch-circuit selection current.

<h3>What is a hermetic refrigerant motor-compressor?</h3>

A hermetic refrigerant motor-compressor can be defined as a mechanical device that is designed and developed by combining a compressor and motor in a single outer-welded steel shell.

Basically, a hermetic refrigerant motor-compressor is used in the following areas:

  • Household refrigerators
  • Freezers
  • Heat pumps
  • Air coolers
  • Water cooling equipment.
  • Small refrigeration equipment.

According to HSE, the nameplate of a hermetic refrigerant motor-compressor that is designed to operate continuously at currents greater than 156% of the rated-load current is marked with branch-circuit selection current, so as to ensure safety for end users and technicians.
