A pitot-static probe will be used to measure the velocitydistribution in a water tunnel at 20°C. The two pressurelines from the probe will be connected to a U-tube manometerthat uses a liquid of specifi c gravity 1.7. The maximumvelocity expected in the water tunnel is 2.3 m/s. Your job isto select an appropriate U-tube from a manufacturer thatsupplies manometers of heights 8, 12, 16, 24, and 36 in.The cost increases signifi cantly with manometer height.Which of these should you purchase?
A pipe inclined at 45° to the horizontal (Fig. 2) converges over a length l of 2 m from a diameterd1 of 200 mm to a diameter d2 of 100 mm at the upper end.

The relative density of mercury is 13.6 and the leads to the manometer arefilled with the oil.
What is the volume flow rate for water (viscosity= .0010 Pa×s) through a length of pipe L= 0.60m and pipe radius r= 1.03cm if the pressure difference across this length of pipe is 5.2 kPa? Note that 1 kPa= 1000 Pa. What would the volume flow rate be if the same pipe had a radius that is reduced by 21% (i.e. the radius is 79% of its previous value)? Let's call this flow rate Q1. What is the ratio of Q1 to the original flow rate Q? Express this as a decimal number.

The flow rate of water in a garden hose is measured using the bucket-andstopwatch method. Filling a 5-L bucket takes 75 seconds. If the inner diameter of the hose is 10 mm and the density and viscosity of water are approximately 998 kg m-3 and 0.9 cP, respectively, (a) is the flow inside the hose laminar or turbulent? (b) If the flow rate is adjusted such that the flow is with Re = 2100, how long would it take to fill the same bucket?

In a cavitation system, it usually occurs in the hydraulic element called the pump. In the presented system, it is desired to determine the maximum height H, for which there is no cavitation, and with this condition, determine the different parameters. For this, it is known that the system moves water at a flow rate of 0.056m³/s at a temperature of 40°C. The energy loss between the suction pipe inlet and the pump is 2.0 N-m/N and between the pump outlet and the upper vessel is 3.8 N-m/N. Both ducts are 6" 40-gauge steel. The vapor pressure of water at 40°C is 0.078 kgf/cm² (abs). The specific weight of water is 9.76 kN/m³. Determine a) The height H for the limit condition of no cavitation of the pump b) the energy per unit of weight provided by the pump to the fluid c) the pressure at the pump outlet d) the power transmitted by the pump to the fluid hydraulic power
