1. A 10-cm-diameter siphon tube is used to empty the reservoir and discharge it into the air (Figure below). If the total head loss between the tube's intake and the summit (S) is 1.5 m and between S and the discharge end is 2.5 m, determine the discharge in the 20-m-long tube and the water pressure at the summit. (Assume T=20 °C) 2 m S J///// 7m

A 2-inch diameter hose is conveying water at a flow rate of 20 gpm from point A to point B. The pressure at point A is 40 psi. The elevation at point A is 20 ft above mean sea level (MSL) and the elevation at point B is 18.5 ft above MSL. The hose is 100 ft long. Determine (a) pressure at point B if there is no head loss, (b) pressure at point B if head loss is 1 inch per foot of pipe length. (c) Compare pressure at B with and without headloss - what impact does head loss have?

An engineer is designing a cooling jet for a manufacturing process that requires water at 60 °F to be discharged from the nozzle shown below at a rate of 81 gallons/minute. (a) What gage pressuren psi) at Point A is required to produce the desired flowrate? (b) After initial testing, it was determined that air should be used instead of water for the cooling process. However, the engineer is concerned that compressibility could affect performance. Explain how you would modify the Bernoulli equation to account for the effect of air being a compressible fluid.
