The air is now compressed in a polytropic process to 400kPa and 140oC. Determine the amount of heat transfer and identify if it is the heat loss or gain during this process.
The crate slides down the section of the spiral ramp such that r = (0.5z) ft and z = (100 - 0.1t2) ft, where t is in seconds. If the rate of rotation about the z axis is ? = 0.04pt rad/s, determine the magnitudes of the velocity and acceleration o
A tank contains 2500 m3 of salt solution, with a salt concentration of 20 kg/m3. At time zero, salt free water starts to be pumped into the tank at a rate of 20 m3/min.

An oil pipeline was constructed to transport an oil with SG = 0.8 for a distance of 10 miles. The country was hilly, so the line made many ups and downs. These may be considered equivalent to 10 rises of 200 ft, followed by descents of 200 ft.
Calculate the electric field at the center of a square 53.0 cm on a side, if one corner is occupied by a +48.0 µC charge and the other three are occupied by -22.0 µC charges. (Assume the center of the square is at the origin and the po
