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.

Solve the following problems. Show your correct and complete solution for this problem. Box your final answers and express in two decimal places. Sketch the schematic diagrams. An adiabatic rigid steam tank has expansion valve. Initially, steam is at 1MPa and 350C. Suddenly, the expansion valve was opened until the tank became empty. If the temperature of steam flowing in the expansion valve is 300C, find the pressure in the valve.
