A finned-tube, cross-flow heat exchanger is to use the exhaust of a gas turbine to heat pressurized water. Laboratory measurements are performed on a prototype version of the exchanger, which has a surface area of 8 m2 , to determine the overall heat transfer coefficient as a function of operating conditions. Measurements made under particular conditions, for which m 1.5 kg/s h = , Th, i = 325°C, m 0.5 kg/s c = , and Tc, i = 25°C, reveal a water outlet temperature of Tc, o = 125°C. What is the overall heat transfer coefficient of the exchanger?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
