Determine the enthalpy change and the entropy change of nitrogen per unit mole as it undergoes a change of state from 225 K and 6 MPa to 320 K and 12 MPa,
(a) By assuming ideal-gas behavior and
(b) By accounting for the deviation from ideal-gas behavior through the use of generalized charts.
Suppose a survey of retailers is conducted this year to determine whether the price of USDA All Fresh beef has increased. The Excel output of the results of the survey are shown here. Analyze the output and explain what it means in this study. An ..

A winding drum is accelerated from 480 to 840 rpm in a time of 2 s. Acceleration continues at the same rate for a further 4 s after which the drum continues rotating at a steady speed. Calculate the time taken to complete the fi rst 200 revolution..
If water leaves the basement at 88C, determine the rate of heat loss from the weather.
Air at 40C flows over a 2m long flat plate with a free stream velocity of 7 m/s. Assume the width of the plate (into the paper) is 0.5m. If the plate is at constant temperature of 100C,
