An engine has a piston with a surface area of 17.31 in2 and can travel 3.44 inches. What is the potential change in volume, displacement (\Delta VΔV) , of the cylinder?

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false

An electrical kettle is made out of stainless steel,weighs two pounds (when empty) with a heating element that consumes 2 kw of electricity. assuming that the water and the kettle are at the same uniform temperature at any moment of time, calculate the shortest possible time to bring 2 quarts of water from room temperature to the onset of boiling.
