Air is flowing over a flat plate at a flow rate of 500 cfs and a temperature of 20.0 C. The flat plate is the back of a piece of sensitive equipment that generates heat (500 W) when it operates, but unfortunately it will malfunction if it heats up above 40.0 C. If the plate is 1 m, calculate the heat transfer coefficient necessary to ensure that the equipment operates properly. A turbine operates by the impact of a high velocity jet of steam at atmospheric pressure against the turbine blades. The steam leaves the turbine at a lower velocity. If the entry velocity to turbine is V. = 317 m/s, and the exit velocity from turbine is V. = 126 m/s, find the amount of work in Joules/Kg performed by the turbine. List all assumptions. Hint: This process all takes place at atmospheric pressure
