Determine the force on the piston of Fig. 5.42a due to shear and the leakage from the pressure chamber for U=0.
An HRT boiler is 4766mm long and 3533mm in diameter. It has 66 steel tubes with a diameter of 9mm. The total dry weight of the boiler is 2.565 tonnes. 4 bolts are to suspend the boiler. If each bolt has to be strong enough to support 1/2 the weight of a filled boiler, what will be the diameter of the bolts? Note: each bolt m
Two vertical forces are applied to a beam of the cross section shown. Determine the maximum tensile and compressive stresses in portion BC of the beam.
A beam of cross section shown is extruded from an aluminum alloy for which σy = 310 MPa and σu = 480 MPa. Using a factor of safety 3, determine the largest couple which may be applied to the beam when it is bent about the z axis.
Problem description A source of water supply water with a Cationic content ( and Anionic content also ) of 123.75 ppm of CaCO3, and a Silica content ( SiO2 ) of 55.6 ppm of CaCO3. The water will be treated using a demineralizer that has two ionic exchange resins : the Anionic and the Cationic ones. The first has a capacit
Consider the steady flow of a Casson Fluid through a rigid circular pipe of radius a, driven by a pressure gradient, show velocity is given by... Please see attachment
Consider a 4-in square steel bar subjected to transverse biaxial tensile stresses of 20 ksi in the x direction and 10 ksi in the y direction. (a) Assuming the bar to be in a state of plane stress, determine the strain in the z direction and the elongations of the plate in the x and y directions. (b) Assuming the bar to be in a s
A large stationary Brayton cycle gas-turbine power plant delivers a power output of 100MW to an electric generator. The minimum temperature in the cycle is 300K, and the maximum temperature is 1600K. The minimum pressure in the cycle is 100 kPa, and the compressor pressure ratio is 14 to 1. The compressor has an isentropic effic

Calculate the rates of strain, vorticity, and rates of dilatation for 3 flows. a) u=cx, v=cy, w=-2cz b) u=c, v=w=0 c) u=2cy, v=w=0
Two infinite parallel plates are separated by a distance h. The space between them is filled with a Newtonian fluid: density (rho), viscosity (mu). The lower plate is fixed, but the upper plate executes a sinusoidal motion. (U=A*sin(omego*t). Calculate the velocity field between the plates, and plot some representative profiles.
In a nuclear power plant the cooling tower system must be run on a closed cycle. That is, the air exiting the tower passes over cooling coils to return it to its initial condition prior to reentering the tower. Air at 20 degrees C and 40% relative humidity enters the tower at a rate of 1.3 x 106 kg/sec. Water enters the tower
Air at 150Pa and 310K enters a compressor of inlet diameter 2cm. The Compressor raises the pressure to 3.5 times the inlet pressure and has an outlet diameter of 5cm. Determine the exit temperature and power input required, if the mass flow rate of air is 100kg/hr.
