The momentum equation for a control volume fixed in space is given by:
/t∰d + ∯(⋅d)S=−∯(p−p[infinity])dS+∰d+visco us
Show how this equation would need to be modified if it were applied to each of the following (different) scenarios:
a. A control volume defined in a flow at steady state for which this no fluid is passing the boundaries.
b. A control volume defined in a flow at steady state for which gravitational forces and pressure forces can be neglected.
c. A control volume defined in a flow at steady state where the friction on a wall boundary can be neglected.
d. A control volume defined around a fluid in an open tank fitted with a pinhole at the bottom from which fluid leaks out from over time.
e. A control volume defined around a steady state flow that is only pressure driven.

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.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
