Problem: A compound cylinder is composed of a tube of 250mm internal diameter at 25mm wall thickness. it is shrunk on to a tube of 200mm internal diameter. the radial pressure at the junction is 8 N permmsquare. Evaluate the variation of hoop stresses across the wall of the compound cylinder, if it is under an internal fluid pressure of 60 N permmsquare. Take e = 200 GPa and m=3

To determine the heat transfer characteristics of a cylinder under cross flow conditions when the cylinder is isolated.
Calculate the static thrust of the turbojet engine having mass flow 88lbm/sec the ratio of air and fuel mass flowing into the turbojet is 50:1 and it's exhaust plane the velocity is 1640 ft/sec and pressure is same as ambient pressure?
Air enters a turbine at 40 kN/m2, 900 C, and leaves at 10 kN/m2. The flow is reversible and adiabatic. Inlet velocity is quite low and outlet velocity is 150 m/s through a cross-sectional area of 0.20 m2. Calculate the power output in kW.
