A 6.44 kg steel ball is at a height of 8.12 meters above the floor, traveling at a velocity of 4.69 m/s, and has an internal energy of 1.86 kJ. Determine the energy (E) of the ball in kilojoules.
A horizontally oriented copper rod length of l=1m is rotated about avertical axis passing through its middle. what is number of rps at wich this rod ruptures?
A plate, 0.001 in distant from a fixed plate, moves at 2 feet per seconds and requires a force of 0.04l bar per feet square to maintain this speed. determine the fluid viscosity of the substance between the plate.
A steel cylinder with an internal radius of 50mm is designed to carry a maximum stress of 400 MPs. It is subjected to an internal pressure of 80 MPs.(i) Determine the required wall thickness.
During the process, the pressure and specific volume are related by pv = constant. For the refrigerant, determine the work and heat transfer per unit mass, each in KJ/kg.
Calculate the change in internal energy of the gas. Remember it is an ideal gas in a constant temperature bath.
