2- The system in the figure below is at 20°C temperature. Determine the pressure at point A in pounds per square foot. Oil SG = x T 6 in + Mercury Water 10 in in Pa 14.7 lbffin² V Water

Plot the variation of pressure with area for four different pump speeds. COURE NAME: THERMOFLUIDS

Water flows in a pipe and nozzle arrangement, having 0.1 diameter pipe and 0.05 m diameter nozzle that discharges to the atmosphere. Exit velocity at the nozzle is 84 m/s.    a) Calculate the pressure at point 1. b) Pressure when the device is inverted.

Higher volumetric efficiency pumps have very lesser slip losses.   Select one: True False

3)

Indicate if it is True or False. Two endlessly long flat plates, separated by 3 inches in distance but with a thickness of 5 inches, each transport alcohol (5 m/s, 1 Pa·s, S.G. 0.89 (ref. water at 4 degrees Celsius) to a given location with a specific velocity. The Reynold's number is something in the number of 90-100.

What is the pipe pressure (pa)? Given the S for Mercury is 13 and S for fluid =3.4

Number 4 pls

A surface condenser deals with 12000 kg of steam per hour. Air leakage into the condenser is found to be 4 kg/hr. The vacuum and temperature at the air pump suction are 700 mm of Hg and 36°C respectively. The barometric pressure is 760 mm Hg. Compute the volumetric capacity in m'/min of wet air pump.

Which factor has the greatest impact on flow? a. viscosity b. radius of the vessel c. pressure gradient d. length of the vessel
