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.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
