Problem 5.3: Following a procedure analogous to that in Example 5.2, obtain an expression for the coefficient of thermal expansion based on the van der Waals equation of state. Use the result to calculate the value of β for oxygen at 20 °C, 30 bar. Problem 5.4: Using the volume-temperature relationship for liquid acetone in Example 5.6 calculate the amount of heat and work involved when acetone is compressed isothermally and reversibly from 1 bar, 20°C to 10 bar. Problem 5.5: Estimate the constant-pressure heat capacity of oxygen at - 50 °C, 38 bar, using the truncated virial equation. Hint: Use the truncated virial to calculate the enthalpy at two pressures near - 50 °C, 38 bar, then obtain the heat capacity by numerical differentiation.
The coil is placed so that its axis of revolution is perpendicular to a uniform field, as shown in Figure P12.1.10. If the flux per pole is 0.02 Wb, and the coil, consisting of 2 turns, is revolving at 1800 r/min, compute the maximum value of the ..

Compute the pull on the plunger for g = 1.25 cm.
a. What alarms would you add to the vaporizer control scheme shown in Figure? Indicate whether the alarm would signal high or low conditions, what the alarm would signify, and what operator response would be required in each case.
Problem 1: For the circuit given in Figure 1 the power factor is 0.72 lagging and the power dissipated is 375 W.
A plant is producing 10,000 metric tons per year (10 kt/y or 10 kMTA) of a product. The overall yield is 70 wt% (0.7 kg of product per kg raw material). The raw material costs $500/metric ton, and the product sells for $900/metric ton. A process m..
