A pump supplies 40 L/min of water through 30 m of 2.54 cm galvanized pipe. The pipe has one fully open globe valve and two 90o standard elbows. Water is delivered at 140 kPa to a tank located 15 m above the pump intake. What is the pump motor power requirement if the combined pump and motor efficiency is 0.70? Assume the temperature of the water is at 20oC with kinematic viscosity and absolute viscosity at 1.006×10-6 m2/s and 0.9934×10-3 Ns/m2, respectively

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.

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
