You are engineering a feedwater system for a power plant and have decided to use a water tower. The plant must be supplied with 100 GPM at a pressure of 75 PSIG. If a 6- inch inner diameter commercial steel pipe is used as the supply line, what must the water tower height be? The very large reservoir at the top of the tower is at atmospheric pressure and 30 °C. The distance from the plant, L, is 1 km. Neglect minor losses

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
