3 .Consider the incompressible flow of an ideal fluid having a density ρ = 1600 kg / m3 (figure 3). We give: P1 = 2 105Pa, P2 = 3 105Pa, V2 = 1 m / s and V1 = 0.5m / s. Determine the net power of the pump to ensure a volume flow Qv = 0.01 m3 / s.

Que. 5.6 A centrifugal pump having an impeller of 35 cm outside diameter rotates at 1000 rpm. The vanes are radial at exit and are 7 cm wide. The velocity of radial flow through the impeller is 3 m / sec. The velocity in the suction and delivery pipes are 2.5 m/s and 1.5 m / s respectively. Neglecting frictional losses determine the height through which pump lifts the water and the horse 3 - power the pump

Consider a flow of SAE 30W oil through a 12-cm-diameter pipe. For SAE 30W oil, take p=891kg/m³. u= 0.29 kg/m-s at 20 °C, and μ = 0.01 kg/m-s at 100 °C, and π = 22/7. 4. For what flow rate in m³/h would a transition to turbulence take place at 100°C? Round the answer to one decimal place. The flow rate is m³/h.

8.14 A fluid flows through a horizontal 0.1-in.-diameter pipe. When the Reynolds number is 1500, the head loss over a 20-ft length of the pipe is 6.4 ft. Determine the fluid velocity.

Water is pumped at steady uniform flow rate of 0.01 m³/s through a horizontal smooth circular pipe of 100 mm diameter. Given that the Reynold number is 800 and g is 9.81 m/s², the head loss (in meters upto one decimal place) per km length due to friction would be......

A 600mm diameter pipe, 720m long carries water at the rate of 2.5m/s. What is the water hammer pressure if the valve is closed in 1.2 seconds? Use Ewater = 2.2x109Pa and pw = 1000kg/m3.

Water is flowing in AF pipe (Figure 1) at a velocity of 2 m/s and a pressure of 102400 Pa, the pipe length is 100 m. If the water pressure needs to be at a pressure of 1.6 atm on a lower level. What should be the different in elevation between the upper and lower levels in order to achieve this pressure? Take the density of water 1000 kg/m3 and gravity is 9.81 m/s2, consider the energy loss.

A water pipe having a 2.33 cm inside diameter carries water into the basement of a house at a speed of 0.887 m/s and a pressure of 241 kPa. If the pipe tapers to 1.27 cm and rises to the second floor 7.37 m above the input point, what are the (a) speed and (b) water pressure at the second floor? (a) Number i Units (b) Number i Units
