A piston-cylinder device is insulated and contains 0.005 m3 of saturated liquid water at a constant pressure of l50 kPa. An electric resistance heater inside the cylinder is now turned on, and 1800 kJ of energy is transferred to the steam.
Determine the entropy change of the water during this process, in kJ/K.
Determine the magnitude of the horizontal and vertical components of the force of the water on the gate.
Evaluate the shearing and normal stresses at points H and J located at the ends of the horizontal and vertical diameters of transverse section located 2.5 in. to the left of bearing B.
