Pure component ther 1.8 - promblems air initially at 1 atm is expanded in a piston cylinder arrangement to twice its initial volume. the temperature is held constant at 100°c. find the heat added and work done. 1. air enters an adiabatic turbine at 1000°c and 10 atm and exhausts at 1 atm. the turbine efficiency is 75% compared with isentropic operation. determine the mass flow rate of air needed to produce 75 mw of power.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
