Water flows steadily through the nozzle shown, discharging to the atmosphere. Calculate the horizontal component of force in the flanged joint. Indicate whether the joint is in tension or compression.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
