Consider incompressible, frictionless flow of a fluid in a horizontal piping. The pressure and velocity of a fluid is measured to be 150 kPa and 1.25 m/s at a specified point. The density of the fluid is 700 kg/m3. If the pressure is 140 kPa at another point, the velocity of the fluid at that point is (a) 1.26 m/s (b) 1.34 m/s (c) 3.75 m/s (d ) 5.49 m/s (e) 7.30 m/s
A pump increases the pressure of water from 100 kPa to 1.2 MPa at a rate of 0.5 m3 /min. The inlet and outlet diameters are identical and there is no change in elevation across the pump. If the efficiency of the pump is 77 percent, the power supplied to the pump is (a) 11.9 kW (b) 12.6 kW (c) 13.3 kW (d ) 14.1 kW (e) 15.5 kW
Here, air (105 kPa) at 37 degrees celcius is flowing upward in a 6cm diamater inclined duct, at a rate of 90 L/s. In this case the density of air is 1.1 kg/m3. The diameter of the duct reduces to 4cm through a reducer and a pressure charge occurs. This pressure change is measured by a water manometer. The elevation difference between the points where the two arms of the manometer are attached is 0.2 meters. What is the differential height between the fluid levels in the two manometer arms?
