imagine a pipe that splits into a Y where each upper branch of the Y is at a 45 degree angle from the main stem. The inflow is through the main stem base of the Y, where the pipe is0.3 m diameter and has an upstream pressure of 380 kPa. One of the branches of the Y is a 0.1m diameter pipe where the flow exits to atmospheric pressure. The other branch of the Y is a 0.2m diameter pipe where the flow goes into other piping at a pressure of 200 kPa. Determine the candy reaction forces. You may assume the flow is steady state and neglect shear stress and weight.

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.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
