Which of these is shown in the photo below?

Arte-miy333 [17]

Answer:

Option C

Explanation:

The image given in the question represents an overflow tank

Since a water pump has rotor and blades (which is not visible in the given image), hence, this image is not of water pump.

The surge tank has a different structure as compared to that of overflow tank

Radiator looks like a metallic structure with parallel blades.

Hence, option C is correct

/ Air enters a 20-cm-diameter 12-m-long underwater duct at 50°C and 1 atm at a

Digiron [165]

Answer:

A) EXIT TEMPERATURE = 14⁰C

b) rate of heat transfer of air = - 13475.78 = - 13.5 kw

Explanation:

Given data :

diameter of duct = 20-cm = 0.2 m

length of duct = 12-m

temperature of air at inlet= 50⁰c

pressure = 1 atm

mean velocity = 7 m/s

average heat transfer coefficient = 85 w/m^2⁰c

water temperature = 5⁰c

surface temperature ( Ts) = 5⁰c

properties of air at 50⁰c and at 1 atm

= 1.092 kg/m^3

Cp = 1007 j/kg⁰c

k = 0.02735 W/m⁰c

Pr = 0.7228

v = 1.798 * 10^-5 m^2/s

determine the exit temperature of air and the rate of heat transfer

attached below is the detailed solution

Calculate the mass flow rate

= p*Ac*Vmean

= 1.092 * 0.0314 * 7 = 0.24 kg/s
