11. A gravity settling tank is to be used to clean waste water from an oil refinery. The waste water contains 1% oil by volume as small droplets ranging in size from 100 to 1000 microns which will be removed from the water before the latter is to be discharged into the river. The tank is of rectangular section 2 ft wide by 4 ft deep with provisions for smooth continuous discharge of clean water and skimming off of oil at the surface of the discharge end. If 10,000 gal/min of waste water is to be cleaned of oil droplets, specific gravity of oil 0.87, the length of the settling tank is c. 5000 ft d. 4000 ft a. 4500 ft b. 4850 ft

Q6The large tank holds 300 gallons of brine solution. Salt was entering and leaving the tank; a brine solution was being pumpedinto the tank at the rate of 3 gal/min; it mixed with the solution there, and then the mixture was pumped out at the rate of 3gal/min. The concentration of the salt in the inflow, or solution entering, was 2 lb/gal, so salt was entering the tank at therate Rin 5 (2 lb/gal) . (3 gal/min) = 6 lb/min and leaving the tank at the rate Rout 5 (A/300 lb/gal) . (3 gal/min) 5 A/100 lb/min.According to this information, if 50 pounds of salt were dissolved initially in the 300 gallons, how much salt is in the tankafter a long time?

A storage tank of a treatment water has a holding capacity of 750 m' up to an overflow point. The treatment water having silica content of 0.003 mg /L is flowing in to a tank at a rate of 30 L/sec. the out flow from the tank to the high pressure boilers is 30 L/sec. With time the quality of treatment water increased to 0.025 mg/L. Assuming that the inflow in to and out flow from the tank remains constant at 30 L/sec, calculate the time required for the silica content in the storage tank to increase to 0.01 mg/L.
A pump pumps 0.200 ft®/s of brine solution having a density of 1.15 g/cm³ from an open feed tank having a large cross-sectional area. The suction line has an inside diameter of 3.548 inches and the discharge line from the pump a diameter of 2.067 inches. The discharge flow goes to an open overhead tank and the open end of this line is 75 feet above the liquid level in the feed tank. If ft - lb: the friction losses in the piping system are 18.0 what pressure must the Ibm pump develop and what is the horsepower of the pump if the efficiency is 70%? The flow is turbulent.
