Answer:

Between 35°– 45°

Explanation:

In the vertical position, Point the flame in the direction of travel. Keep the flame tip at the correct height above the base metal. An angle of 35°–45° should be maintained between the torch tip and the base metal. This angle may be varied up or down to heat or cool the weld pool if it is too narrow or too wide

What is referred to as "Pyroelectric" materials?

aliina [53]

Answer and Explanation:

Pyroelectric material

Pyroelectric materials have special property of generating potential difference (although it is very less ) when these material are treated with heat or when celled down.

The potential difference generated is for very less time

The generation of potential difference is due to change in position of atoms after heating or cooling.

A three-phase 12 HP motor is 90% efficient with a .89 lagging power factor. What is the required rated input apparent power for

Feliz [49]

Answer:

The required rated input apparent power is 14.98 HP

Explanation:

Real power input = real power output ÷ efficiency

real power output = 12 HP

efficiency = 90% = 0.9

Real power input = 12 ÷ 0.9 = 13.33 HP

Apparent power input = real power input ÷ power factor = 13.33 ÷ 0.89 = 14.98 HP

A method used to control density and overcrowding by restricting setbacks, building height, or ratio of open area is known as __

Mamont248 [21]

Answer:

Bulk zoning.

Explanation:

Zoning is a method used by municipal authorities or government authorities to divide a land area into zones. It is a urban planning method. There are several types of zoning; bulk zoning being one of them.

Bulk zoning can be defined as a set of regulations used to control lot size, ratio of floor area, open space, yards, setbacks, bulding height, etc. These setbacks and restrictions, then, help authorities to determine maximun size of a building on a zoning area, and also the positioning of the building.

Therefore, bulk zoning is the correct answer.

There are four main exit strategies for ending your involvement with a company: selling the company, liquidating the company by

vredina [299]

I am assuming there is no correct answer rather preference so here:

I would choose to sell stock to private investors so I as the (assuming) CEO, could receive a lump sum profit and the company could still stay afloat keeping any and all employees employed. Additionally the brand name would not be impacted as severely as if you were to just sell out to the public.

A mixing chamber receives a steady flow of water from different parts of a processing plant. It has two inlets and one outlet. T

alex41 [277]

Answer:

hello your question has some missing information attached below is the missing information

answer :

a) 9.17431 kg/s

b) 2598.4374 kW

Explanation:

<u>a) Calculate mass flow rate at inlet 1 </u>

Given data :

AV1 = 0.01 m^3/s

pressure ( P1 ) = 5 bar , temp ( T1 ) = 150°C

therefore : m1 = AV1 / v1 ------ ( 1 )

where : v1 = 0.00109 m^3/kg ( value gotten from compressed table )

back to equation 1

m1 = ( 0.01 m^3/s / 0.00109 m^3/kg ) = 9.17431 kg/s

<u>b) Calculate the rate of heat transfer </u>

first determine mass balance

m3 = m1 + m2

= 9.17431 + 19 = 28.17431 kg/s

apply the energy balance equation to determine the rate of heat transfer

m1*h1 + m2*h2 = m3*h3 + Q

∴ Q = m1*h1 + m2*h2 - m3*h3 ------------ ( 1 )

where :

h1 = 632.266 kJ/kg value gotten from compressed water table

h2 = 2812.45 kJ/kg value gotten from superheated steam table

h3 = 2010.2965 kJ/kg value gotten from saturated pressure table

input values into equation 1 above

Q = 2598.4374 kW . the energy moves from the chamber to the surroundings
