(ii) What pressure would the sensor from (c) measure at that same point on the airfoilsurface? Assume that the local velocity is the same as found in (c).(Ans. 101,200 Pa(a), 177.4 km/hr, 101.2 m/s, 54,940 Pa(a), 51,170 Pa(a))4.2The bellmouth inlet shown in the drawing is usedto measure the flow rate into an air compressor. If the flow rate is 12,000 cfm (ft3/min), whatreading h will the U-tube give in inches of water? Assume incompressible flow.(Ans. 4.59 in.)

4.24.3Calculate the flow rate in m3/s for the unknown liquid in the pipeline shown. The two vertical tubesare open to the atmosphere. Assume uniform flow and neglect friction.(Ans. 0.139 m3/s)4.4An L-shaped glass tube is lowered into a flowing liquidstream, as shown in the drawing. The liquid is observed torise 2 cm in the tube above the free surface of the liquid. What is the velocity of the stream at the depth where themouth of the tube is located?(Ans. 0.63 m/s)4.5The drawing shows a section through a sluice gate which is used to control the flow of water in achannel. The channel has a rectangular cross section with a width of 10 m in the horizontaldirection. The gate spans the full width of the channel. For the conditions shown, what is thevolume flow rate of water in m3/s through the gate? Assume uniform velocity well upstream anddownstream of the gate and neglect friction.(Ans. 554 m3/s)
