Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

2. Calculate the energy transfer rate in kilowatts for the problem no. 1 if the given heat transfer
area is 2m? and the temperature difference across the wall will be increased by 400 K.

Tony Stark, a brilliant inventor, has designed a special suit/armor that has an inbuilt small but concentrated high-powered reactor as its power source. The only problem is there is lot of heat generated in the reactor that needs to be cooled for the suit to be actually wearable. Stark needs a heat exchanger mounted on the suit to dissipate the excess heat generated in the reactor. He found a 10 cm x 20-cmx5-cm space on the armor for the heat exchanger. He chose a liquid (specific heat 2.8 kJ/kg°C) that circulates around the reactor and takes heat away from the reactor and then enters the heat exchanger with mass flow rate of 0.2 kg/s at a temperature of 180°C. It comes out of the heat exchanger at a temperature of 10°C. The other fluid in the heat exchanger is a phase-changing liquid that remains at -23°C as it changes phase from saturated liquid to a mixture of liquid and vapor during the heat exchange process. The latent heat vaporization for the phase-changing liquid is 560 kJ/kg.…
