The tank shown has a 180 mm inside diameter and a 12 mm wall thickness. Knowing that the tank contains compressed air under a pressure of 8 MPa, determine the magnitude T of the applied torque for which the maximum normal stress in the tank is 75 MPa.
Sketch the T-s diagram for the cycle (put labels and appropriate information)
a hydraulic system has a mechanical advantage of 4. If a smaller piston has a diameter of 5 inches what is the diameter of the larger piston?
A power plant operates a regenerative Rankine cycle with a reheat, one closed and one open feedwater heater and has a net power output of 1.2 x 109 Btu/hr. When the steam exits the boiler it's temperature is 1000°F and its pressure is 1400psi...
