Concept explainers

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

The suction diameter of 60mm reads 2psi vaccum and 50mm diameter discharge with 250kpag. The suction water level is 5m above water pump center line and discharge water level is 25m above the pump center line. The total head loss at suction and discharge is 2m. If discharge is 0.01m3/s, find the horsepower needed to pump the water for 80% pump efficiency. ANSWER: 8.15 hp
A centrifugal pump is pumping water at the design conditions with a flowrate of 2300 gpm and a tangential velocity of U2=65ft/s. The flow passage area at the outlet is A2=1ft2. About 5% of the flow is recirculated internally and pumped again. The actual head rise of the pump is 94ft and the blade angle at outlet is 28º. Knowing that the total number of blades is Zb=24, the power needed to operate the pump is Ps=65hp. Take g = 9.81 m/s2 = 32.2 ft/s2 & ρw = 998 kg/m3 =1.94 Slug/ft3. Estimate the theoretical head of the pump in ft using Stodola’s formula (Hi). Determine the mechanical efficiency of the pump (ηm).
