An existing bubble-cap distillation tower has an ID of 8 ft and a tray spacing of 30 in. The tower is operating under a pressure of 70 psig, and a slot liquid seal of 2 in. is maintained. At the point of maximum volumetric vapor flow, the molecular weight of the vapor is 100, the rate of vapor flow is 1500 lb mol/h, the liquid density is 55 lb/ft3, and the temperature is 175°F. The pressure drop through the tower is negligible, and the ideal gas law is applicable to the rising vapors. Approximately what percent of the maximum allowable flow rate is being used in the tower?

Then the monkey on the right begins to climb the rope while the monkey on the left simply holds on. When the right monkey has raised himself through height h(relative to the floor), what has been the change in the position of the left monkey?
A geometrically similar 200 pump having a similar efficiency curve is used to pump water through 112.5 m of 150 mm pipe, f = 0.025. The static lift is 10 m. Neglecting minor losses in the pipe calculate the flow, head and power required to drive t..
Compute the increase in temperature and entropy if saturated liquid water at 10 kPa is pumped to a pressure of 9.0 MPa, if the pump is 75% efficient (where 100% efficiency would be reversible). You may use constant values and at these conditions.
Estimate the annual operating cost of providing refrigeration to a condenser with duty 1.2 MW operating at -5 ºC. The refrigeration cycle rejects heat to cooling water that is available at 40 ºC, and has an efficiency of 80% of the Carnot cycle ef..
A small atomic bomb releases energy equivalent to the detonation of 20,000 tons of TNT; a ton of TNT releases 4x10^9 J of energy when exploded. Using 2x10^13 J/mol as the energy released by fission of 235U, approximately what mass of 235U undergoe..
