Apiston-cylinder containing steam at 700 kpa and 250°c undergoes a constant pressure process until the quality is 70%. determine per kilogram (a) the work done, (b) the heat transferred, (c) then change of internal energy, and (d) the change of enthalpy

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Fluids at rest possess no flow energy. a)- true b)- false

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
