A rigid tank contains an ideal gas at 300 kPa and 600 K. Now half of the gas is withdrawn from the tank and the gas is found at 100 kPa at the end of the process. Determine (a) the final temperature of the gas and (b) the final pressure if no mass was withdrawn from the tank and the same final temperature was reached at the end of the process.
explain the tapping operation and the steps to follow peripheral milling is performed on the top surface of a
A turbine takes in 2 kg/s neon at 27C and 200 kPa with negligible velocity. The produced work is 75 kW and 30 kW of heat leaks into the turbine from the surroundings. The neon exits at 100 kPa and 230 K. Find the exit velocity of the neon.
A solid round steel shaft, having an outside dameter of 2.002 in., is press or force fitted into the 2.000 in, hole in a gear. The force required to press the two machine parts together is 18,000 lb. What is the diameter of the solid steel shaft duri..

Saturated water vapor is contained in a rigid container. Heat is then added until the the pressure and temperature become 812.075 MPa and 400 °C, respectively. What was the initial temperature of the steam in °C?
Hydrogen flows through a horizontal insulated duct. At section1 the enthalpy is 2400 btu/lbm, the density is .5 lbm/ft^3 and the velocity is 500 ft/sec. at at downstream section, h2= 2240 btu/lbm and density2= .1 lbm/ft^3. No shaft work is done. Dete..
The temperature and heat flux are plotted assuming radial symmetry, that is, even though the sensors are on both sides of the center line, they are plotted from one side only. Discuss whether or not you feel this is a good assumption. If so, are ther..
