Determine the change in specific internal energy
Air is adiabatically compressed in a non flow process from a pressure of 14.7 psia and a temp of 70 deg to 200 psia and 350 deg. if the Cv of the air is 0.171 btu/lbm R, determine the change in specific internal energy of the air and the work done.

Hot water traveling through a thick-walled steel pipe (k=60 W/m·K) is cooled externally by a cross-flow airstream at a velocity of 20 m/s at a temperature of 25ºC.
The bullet goes completely through the target, emerging at only vf= 100 m/s on the opposite side. What is the angular speed of the target just after the collision?

A 2.05 kg frictionless block is attached to an ideal spring with force constant 325 N/m. Initially the spring is neither stretched nor compressed, but the block is moving in the negative direction at 15 m/s. Part A: Find the amplitude of the motio
If 95% and 98% confidence intervals were developed to estimate the true cost of an MP3 player with a known population standard deviation, what differences would they have?
At the exit, the pressure and velocity are 1.45 bar and 360 m/s respectively. Assuming ideal gas behavior for air, determine the heat transfer per unit mass of air flowing through the duct in kj/kg.
