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?
Shows an electric-circuit which is called a phase-lag network. Derive the transfer function and consider the above bock-diagram of figure (3). You are now required to derive the transfer function Y(s)/R(s), by using the signal flow graph meth..
on the basis of the information given ,is it possiple to compute the magnitude of the load that is necessary to produce this change in length?
The temperature of the water drops to 260 F as a result of heat transfer to the surroundings. Determine the final pressure in the tank?
A vessel with a volume of 0.0011 m3 is filled with dry saturated steam at a pressure of 95 kPa. It is then sealed and cooled to 250C. Determine the amount of heat that must be removed.
an ideal rankine cycle produces 100 MW of power. If the steam enters the turbine at 100 bar and 500C and is condensed at 1 bar, determine the flow rate of stream and the thermal efficiency.
showing the two upward pulls of the rings on his hands, each of size 380N. Calculate the angle between the wires supporting the rings and the vertical.
Two slender rods of negligible weight are pin-connected at A and attached to the 18-lb block B and the 80-lb block C as shown. The coefficient of static friction is 0.55 between all surfaces of contact. Determine the range of values of P for which..
