Flash Distillation (or Single-Stage Contact) A mixture of 70 mole % n-pentane and 30 mole % n-heptane is vaporized at 101.325 kPa (absolute) until 60 moles of vapor and 40 moles of liquid in equilibrium with each other are produced. This occurs in a single- stage system and the vapor and liquid are kept in contact until equilibrium is achieved. Calculate the composition of the vapor and liquid. Note: Assume the system exhibits ideal behavior (which it mostly does), e.g. Raoult's Law applies and an Antoine's Vapor Pressure correlation is a sufficiently accurate model of component vapor pressure.

7.40. The cart in Fig. 7.38 has a mass of 2000 kg. It is resting on frictionless wheels on a solid, level surface and encounters no air resistance. At time zero it is standing still, and a jet from a fire hose is used to start it moving. The mass flow rate of the fluid from the fire hose is 100 kg / s, and its velocity relative to fixed coordinates is 50 m/s. The cup on the rear of the cart turns the jet around so that it leaves in the -x direction with the same velocity relative to the cart with which it entered. Calculate the velocity-time behavior of the cart; assume the jet is unaffected by gravity. (This is not a very practical problem, but it is analogous to the more complex and interesting problem of starting a large turbine from rest. All such turbines must be occasionally shut down for maintenance; their starting and stopping behavior is more complex than their behavior running at a steady speed.)

. (Grinding Operations and Grinding Machines) (USCS units) In a centerless grinding operation, the grinding wheel diameter = 8 in, and the regulating wheel diameter = 5.0 in. The grinding wheel rotates at 1500 rev/min, and the regulating wheel rotates at 180 rev/min. The inclination angle of the regulating wheel = 2.3°. Determine the production rate of cylindrical work parts whose diameter = 0.5 in and length = 5.0 in. Solutions used; fr = TD₂N, sin I
