Question
2. A well-insulated piston-cylinder device contains 5 L of saturated water at a constant pressure of 150 kPa. Water
is stirred by a propeller connected to a 500 W motor while a power source that supplied 8A of electrical current
flow through the coil. The propeller and coil are placed in the water for which they are switched ON for 38
minutes. If one-half of the mass of liquid is vaporized to saturation in this process, determine
(a) is this nonflow or steady flow process?
(b) draw the pv and Ts diagrams
(c) voltage of power supply, and
(d) using the same power supply as calculated in (c),
how long it will take in minutes if the device is not insulated
so that heat loss is 400 kJ?
