A simple batch still (one equilibrium stage) is separating a 50 mole feed charge to the still pot that is 80.0 mol% methanol and 20.0 mol% water. An average distillate concentration of 88.6 mol% methanol is required. Find the amount of distillate collected, the amount of material left in the still pot, and the concentration of the material in the still pot. Pressure is 1 atm.

Experiments have been conducted on a metallic cylinder 9.525 mm in diameter and 300 mm long. The cylinder is heated internally by an electrical heater and is subjected to a cross flow of air in a low speed wind tunnel. Under a specific set of operating conditions for which the upstream air velocity and temperature were maintained at V = 7.62 m/s and Tair = 24.0°C, respectively, and the heater power dissipating was measured to be P = 57.2 W, while the average cylinder surface temperature was determined to be Tsur = 80°C. It is estimated that 10% of the power dissipation is lost through the cumulative effect of surface radiation and conduction through the end pieces. Obtain Error between Nuexp and Nucor in %. use the following air properties Viscosity (mu) 0.00001962 kg/m-s Density (rho) 1.086 kg/m3 Thermal conductivity (k) 0.02816 W/m-K Pr 0.701

To make an instant tomato soup, a company makes soup powder from liquid step by a two-step process: concentrating the soup by removing water using a membrane to reach a concentration of 45% water, followed by a spray drying process which leads to a final moisture content of 3%. If the initial liquid tomato soup contains 9.0% solids and fat and enters the membrane separator at 4000 kg/hr, calculate: The flow-rate of the concentrated soup after membrane separation: kg/hr The flow-rate of water removed by the spray drying process (the second stage): kg/hr

If the slurry is filtered using a larger filter press with an area of 15 m2 at a constant rate of 450 L/h, calculate the volume of filtrate that will be recovered and the time it will take to reach a pressure of 1000 kPa.
