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 pump of a water distribution system is powered by a 15-kW electric motor whose efficiency is 95 percent. The water flow rate through the pump is 50 L/s. The diameters of the inlet and outlet pipes are the same, and the elevation difference across the pump is negligible. If the pressures at the inlet and outlet of the pump are measured to be 100 kPa and 300 kPa (absolute), respectively, determine the mechanical efficiency of the pump. Water 300 kPa 100 kPa 150 Ls motor Motor 15 kW The mechanical efficiency of the pump is %.
The drive is by V-belts from an electric motor running at 1500 r.p.m. A compressor, requiring 75000W is to run at about 500 r.p.m. The diameter of the pulley on the compressor shaft must not be greater than 1.2 meter while the centre distance between the pulleys is limited to 1.85 meter. The belt speed should not exceed 1500 m/min. Determine the number of V-belts required to transmit the power if each belt has a cross-sectional area of 3 cm2, density 1100 kg/m3 and an allowable tensile stress of 3 MPa. The groove angle of the pulley is 50°. The coefficient of friction between the belt and the pulley is 0.3. Calculate also the length required of each belt.

Large wind turbines with a power capacity of 8 MW and blade span diameters of over 160 m are available for electric power generation. Consider a wind turbine with a blade span diameter of 100 m installed at a site subjected to steady winds at 8 m/s. Taking the overall efficiency of the wind turbine to be 39 percent and the air density to be 1.25 kg/m³, determine the electric power generated by this wind turbine. Also, assuming steady winds of 8 m/s during a 24 hour period, determine the amount of electric energy and the revenue generated per day for a unit price of $0.09/kWh for electricity. The density of air is given to be p = 1.25 kg/m³. The electric power generated by the wind turbine is The amount of electric energy generated is The revenue generated per day is $ kWh. kW. K
