Problem 04.037 - Energy balance for water in a piston-cylinder device An insulated piston-cylinder device contains 4.500 L of saturated liquid water at a constant pressure of 175 kPa. Water is stirred by a paddle wheel while a current of 8 A flows for 45 min through a resistor placed in the water. One-half of the liquid is evaporated during this constant-pressure process and the paddle-wheel work amounts to 400 kJ. W H₂O P= constant Wsh www Problem 04.037.a - Find source voltage Determine the voltage of the source. Use data from the steam tables. (Round the final answer to two decimal places.) The voltage of the source is V.
