A phosphate solution [sp. gr. = 1.3, Cp = 0.757 BTU/(lbm. °R), μgc = 2.9 lbm/(ft.hr), kf = 0.3 BTU/(hr.ft.°R)] is used in the production of fertilizer. The solution is to be cooled from 150°F to 140°F using well water, available at 55°F. The phosphate solution flows at a rate of 7000 lbm/hr and has a dirt factor of 0.001 hr ft. °R/BTU. Select an appropriate exchanger and analyze it completely.

A feed of 10 000 kg of soybeans is processed in a sequence of three stages. The feed contains 35wt% protein, 27.1wt% carbohydrate, 9.4wt% fiber and ash, 10.5wt% moisture, and 18wt% oil. In the first stage, the beans are crushed and pressed to remove oil, giving an expressed oil stream and a stream of pressed beans containing 6wt% oil. Assume no loss of other constituents in the oil stream. In the second stage, the pressed beans are extracted with hexane to produce an extracted meal stream containing 0.5wt% oil and a hexane-oil stream. Assume no hexane in the extracted meal. Finally, in the last stage, the extracted meal is dried to give a dried meal of 8wt% moisture. Find the 1. mass in kg of pressed beans from the first stage, the mass of extracted meal from the second stage, mass of final dried meal from the third stage, and wt% of protein in the dried meal. Provide illustration.

What are the "refrigeration and cyogenic plant" EQUIPMENT for Oxygen production in terms of mechanical, electrical, plumbing and safety with a mechanical system and its importance? Elaborate well

An experiment is done on a single cylinder engine whose crankshaft makes two complete revolutions in every cycle and the observation data were recorded for 1 hour duration: Crankshaft revolutions =70000, Indicated mean effective pressure=38*0.7 bar, Engine swept volume=1.1 litres, Brake load on dynamometer=6kg, Brake drum diameter=37*0.8 cm, Fuel used=Diesel, Calorific value of fuel=41*0.75 MJ/kg. What percentage of indicated power is available at the engine output shaft? What will be the Indicated Specific Fuel Consumption (ISFC) in kg/kWh, if the conversion efficiency of heat released in the cylinder to indicated power is [38*0.9] %. If the conversion efficiency is less than or equal to 35%, then use [71]*0.5 % for finding conversion efficiency.

A 5-feet diameter Chimney is designed to handle a flue gas produced in a steam power plant at a rate of 17 lb/s. The barometric pressure is 29.92-inch Hg. Outside air enters the combustion chamber at 90 F. The average temperature of the flue gas inside the Chimney is 572 F and its molecular weight is 30. Cv = 0.35, Rair = 53.342 ft-lb/lb-R. Calculate: 5. The total draft, feet of air. 6. The height of the Chimney, feet

Students did an experiment on Swansea University jet engine. They measured ambient temperature  16  deg C and ambient pressure 1.02 bar, engine RPM 64,664, thrust 17.5781 N, air flow 42.0557 l/s, fuel flow 8.6914 l/h, gauge combustion pressure 0.2942 bar.  The temperature values (deg C) at compressor exit, turbine inlet and exhaust were recorded as 39.84, 869.53, 585.93. Assume density of fuel as 0.8 kg/L. The heating value of fuel is 42580 kJ/kg. The idea gas constant R is 0.287 kJ/kg K, the Cp value for air is 1.005 kJ/kg K and the value of specific heat ratio k is 1.4 Estimate the thrust specific fuel consumption value under ideal conditions (g/N-s) Enter your answer to four decimal places in the box below. answer ASAP would be appreciated
