Air enters a converging-diverging nozzle at a stagnation pressure of 2mpa, a stagnation temperature of 400k, and a mach number of 0.5. the flow is accelerated isentropically through the nozzle to a mach number of 4(station x), passes through a normal shock (x to y), and then flows isentropically to the exit. given a nozzlethroat area of 0.05m2 and exit area of 1m2, find the location of the shock (nozzle area).

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
