Explanation Given: The diameter of the pipe ( d ) is 8 in. The discharge at B ( Q B ) is 600 ft 3 /min . The efficiency ( e ) is 0.6 The head loss in the turbine. h L = 4.5 ft . Calculation: Calculate the velocity at A ( V A ) using discharge ( Q ). Q = V B A B Q = V B × ( π 4 × d 2 ) 600 ft 3 /min= V A [ π 4 ( 8 in . ) 2 ] ( 600 ft 3 min ) ( 1 min 60 s ) = V B [ π 4 ( 8 in . × 1 ft 12 in . ) 2 ] V B = ( 90 / π ) ft/s Consider the water is incompressible and inviscid and the steady flow state and water in the pump is control volume. The point B and C are exposed to atmosphere, so the pressure at these points is zero. p B = p C = 0 The datum is passed through point B , so the datum level at z B = 0 and z C = 45 ft . Apply Bernoulli equation between A and B . p A γ + V A 2 2 g + z A + h pump = p B γ + V B 2 2 g + z B + h turb + h L 0 + 0 + 45 ft + 0 = 0 + ( 90 π ft / s ) 2 2 ( 32

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.

A boiler with 80% efficiency produces steam at 40bar and 500 C at a rate of 1.128kg/s. The temperature of the feed water is raised from 25 C to 125 C in the economizer and the ambient air is drawn to the boiler at a rate of 2.70 kg/s at 16 C. The flue gases leave the chimney at rate of 3 kg/s at 150 C with specific heat of 1.01 kJ/kg.K. The dryness fraction of steam collected in the steam drum is 0.95. 1- Determine the heat value of the fuel. 2- The equivalence evaporation. 3- Draw the heat balance sheet.

A rotating shaft is made of 42 mm by 4 mm thick cold-drawn round steel tubing and has a 6 mm diameter hole drilled transversely through it. The shaft is subjected to a pulsating torque fluctuating from 20 to 160 Nm and a completely reversed bending moment of 200 Nm. The steel tubing has a minimum strength of Sut = 410 MPa (60 ksi). The static stress-concentration factor for the hole is 2.4 for bending and 1.9 for torsion. The maximum operating temperature is 400˚C and a reliability of 99.9% is to be assumed. Find the factor of safety for infinite life using the modified Goodman failure criterion.
