Water (density = 1000 kg/m3) flows through a duct that makes a 180 degree U-shaped bend (see below). Assume that the fluid is incompressible through the duct and the velocity at the inlet is V1 = 24 m/s. Assume that the momentum-flux correction factor at both inlet (point 1) and outlet (point 2) is 2.1. The gage pressures are P1 = 120 kPa at the inlet and P2 = 248 kPa at the outlet of the bend. The inlet is...
Question 18 (10 April 2020) 51.5 kW 12 cm Pump An oil pump is drawing 51.5 kW of electric power while pumping oil with p= 860 kg/m3 at a rate of 0.23 m3/s. The inlet and outlet diameters of the piper are 8 cm and 12 cm, respectively. If the pressure rise of oil in the pump is measured to be 500 kPa and the motor efficiency is 87.5 percent, determine the mechanical efficiency of the pump. Motor 8 cm...
2. A pump delivers 4 m3/min of water from 110 kPa to 350 kPa. Both pipe's gages are on the same level. The inlet and outlet pipe diameters are 16 cm and 13 cm, respectively. The inlet and outlet temperature are both 25°C and mass density of water is 997 kg/m². Calculate the pump work in kW.
Water flows steadily through a curved duct that turns the flow
through angle = 135 degrees, as shown in Fig. 3. The
cross-sectional area of the duct changes from A1 = 0.025 m2 at the
inlet to A2 = 0.05 m2 at the outlet. The average velocity at the
duct inlet is V1 = 6 m/s. The momentum flux correction factor may
be taken as 1 = 1.01 at the duct inlet and 2 = 1.03 at the its
outlet....
asap please, will rate!

A Venturi tube may be used as a fluid flow meter. If the fluid flow rate in m3/s is 1.6 * 10-3 and the radius R1 = 2.4 *10-2 m of the inlet tube is 2.9 times the radius R2 of the outlet tube, and the fluid is water (ρ = 1000 kg/m3), find the pressure difference P1 - P2 in units of kPa. Enter a number with one digit behind the decimal point.
The Venturi tube shown in the figure below may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (p 7.00 x 102 kg/m3) through a hose having an outlet radius of 1.47 cm. The difference in pressure is measured to be P1 P2 1.10 kPa and the radius of the inlet tube to the meter is 2.94 cm (a) Find the speed of the gasoline as it...
