An ideal gas in a tank at 500C and 100kPa is compressed isothermally (at constant temperature) to 1000kPa. What was the work (in J/gmol ) of compression? Water flows through a horizontal hose nozzle from a pressure of 40psig to 15psig. Neglect the initial velocity of the water and any heat transfer. What would be the simplest energy balance to use in calculating the exit velocity of the water in the steady state?
