Compressed gas is used in many circumstances to propel objects within tubes. Let the cross - sectional area of the tube be given by A and the position of the cylinder by s , and assume that the compressed gas is an ideal gas at constant temperature so that the pressure P times the volume is a constant, i.e., P = constant. If the force exerted by compressed gas is assumed to be a conservat ive force, show that the potential energy of this compressed gas is given by V = - P 0 S 0 A · ln( s / s 0 ) , where P 0 is the initial pressure and s 0 is the initial value of s . Model the cylinder as a particle, and assume that the forces resisting the motion of the cylinder are negligible.

Assume you are an observer standing at a point on the track for a period of 30 minutes and are recording the instantaneous speed of each vehicle as it crosses your point. What is the time-mean speed and space-mean speed for these vehicle
In an unconfined aquifer having K = 30/m/day, two observation wells, 3km apart, have water levels of 50 and 40 m, respectively, above the base of the aquifer. Determine the rate of flow.
If it absorbs 100 Joules each cycle from the hot reservoir, how much work does it do. How much heat is given off in each cycle If each cycle takes 0.5 seconds, find the power output of the engine.
Transportation network, A power generator at a dam can send 300 megawatts to substation 1, can send 200 megawatts to substation 2, and can send 250 megawatts to substation 2
Water flows past a triangular flat plate oriented parallel to the free stream. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar boundary layer flow.
Air at 200 kPa and 950 K enters an adiabatic nozzle at low velocity and is discharged at a pressure of 80 kPa. If the isentropic efficiency of the nozzle is 92%, determine the temperature and velocity of the air at the exit.
If the overall gear reduction ratio is 8 to 1, what is the maximum acceleration from rest (in ft/sec^2) for: a) the car with the base engine? b) car with the modified engine? Assume the car is on good dry pavement.
A truck driver used sand to soak up a 1 g spill of lindane (C6H6Cl6). He placed the contaminated soil in an open drum which then filled with 150 L of water during a rainstorm. You test the water and find a concentration of 17 M/L.
There are many parallels between the industrialization of the United States after Reconstruction and the modernization of the American workforce in the last twenty to thirty (20-30) years as it transitions from industry to a service-oriented econo..
