Q- A semi-tubular cylinder of 75mm radius with concave side upstream (drag coefficient = 2.3) is submerged in flowing water of velocity 0.6m/s. If the cylinder is 7.2m long and density of water is 1000kg/m3, what is the drag?
Fluid motor system problem: Water at 10°C is flowing at a rate of 115 L/min through the fluid motor shown in figure below. The pressure at A is 700 kPa and the pressure at B is 125 kPa. It is estimated that due to friction in the tubing there is an energy loss of 4.0 N.m/N of water flowing. At A the tubing entering the fluid motor is a standard steel hydraulic tube having an OD = 25 mm and a wall thickness of 2.0 mm. At B, the tube leaving the motor has OD = 80 mm and wall thickness of 2.8 mm. (a) Calculate the power delivered to the fluid motor by the water. (b) If the mechanical efficiency of the fluid motor is 85 percent, calculate the power output.

An oil flow rate of 0.012 m³/s is required in an industrial process. The flow system includes a pressure tank pushing the oil through 200 m of new ductile iron pipe (DIP: 15 cm diameter, square-edged entrance) to point "2" (atmospheric pressure) as shown in Figure P3.11.11. The sur face of the fluid in the tank (point "1") is at elevation 100 m and the end of the pipe (point "2") is at elevation 106 m. What air pressure will be needed over the fluid to produce the requisite flow? (S.G. (oil) = 0.84, v 2.03 x 106 m²/s, and e = 0.00012 m.)
