A 5 x 5 cm plate is at a constant temperature of 50 ° C and tilted 60 ° to the horizontal. Calculate the heat released by both sides of the plate to the water at 20 ° C. (Only free convection is heat transfer).
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
1. A 5 x 5 cm plate is at a constant temperature of 50 ° C and tilted 60 ° to the horizontal. Calculate the heat released by both sides of the plate to the water at 20 ° C. (Only free convection is heat transfer).
2. The cross flow type heat exchanger has 40 pipes with a diameter of 1 cm. The heat exchanger is 1 x 1 meter in size. Cold water (Cp 4180 J / kg ° C) enters the pipe with a temperature of 18 ° C and an average speed of 3 m / s. hot air as a heat exchanger with a temperature of 130 ° C and an average speed of 12 m / s and a pressure of 105 kPa (cp = 1010 J / kg ° C). if the coefficient of total heat is 130 W / m² ° C calculate:
A. temperature out of the air and air
b. Heat rate that occurs
