- Draw the Temperature & compute the LMTD for CO-CURRENT & COUNTER-CURRENT flow heat exchanger. A single-pass tubular type heat exchanger heats air from 35 C to 80 C. Exhaust gas from DIESEL engine at 350 C is used as heating medium. If the final temperature of exhaust gas leaving the heat exchanger is 140 C, what is the LMTD?A liquid-to-gas counterflow heat exchanger is used to cool gas from 32°C to 18°C. Assuming that the liquid enters at 7°C and leaves at 15°C, calculate the log mean temperature difference in °C. Draw and label the temperature-flow diagram. Round off your answer to three (3) decimal places.The condensing pressure for a Rankine engine is 0.001325 MPavac. Calculate the following for steam flow rate = 1 kg/sec of steam when the steam at the beginning of expansion is at 119.6 deg SH and 4.0 Mpaa. Draw the TS and equipment diagrams for the ideal and actual case and find for the following for the ideal case: Ideal turbine work (KW). Ans.____________________________ Heat rejected at condenser (KJ/sec). Ans.____________________________ Mass of cooling water in kg/sec if cp H2O = 4.18 KJ/kg-K, and inlet temp of water to condenser = 20 deg C, outlet temp is 35 deg C.

- A counterflow heat exchanger is designed to heat fuel oil from 45°C to 100°C while the heating fluid enters at 150°C and leaves at 115°C. Calculate the arithmetic mean temperature difference.The clean U for an exchanger is 770 BTU/(hr 0 F ft2). Its tube area is 550 ft2. After operating for several months, it is heating water from 40 0F to 150 0F at a flow rate of 200 GPM with a heating fluid on the shell entering at 300 0F and exiting at 170 0 F. Has the overall U decreased significantly? how many 1.0 inch diameter, 20 ft long tubes would it take to equal the 550 ft2 area?Project 5: Automobile radiator, condenser, evaporator, air preheater, and cooling tower are common types of direct heat exchangers that also called recuperators. Recuperators may have different types based on the flow arrangement of the hot and cold fluid. Your role in a company that manufactures recuperators heat exchanger is to design a counter-flow recuperator (see Figure.6) that is used in heating, ventilation, and air conditioning (HVAC). Section.1: − Exhaust pipe is 88 ?? diameter. − Exhaust gas enters at 500??. − Water jacket is used and enters at 8??. − The surface heat coefficient of water and gas are ℎ????? = 300 ?/(?2.?) and ℎ??? = 1500 ?/(?2.?) , respectively. − Assume conduction transfer through wall is negligible. − The gas heat specific capacity is ?? is 1130 ?/(??.?). − The water heat specific capacity is ?? is 4190 ?/(??.?). − The flow rate of gas and water are 320 and 1500 ??/h, respectively. − The gas must be cooled to 100??. You need to design a counter-flow…
- with schematic diagram A vacuum refrigeration system consists of a large insulated flash chamber kept at low pressure by a steam ejector which pumps vapor to a condenser. condensate is removed by a condensate to an air vent. warm return water enters the flash chamber at 13 c, chilled water comes out of the flash chamber at 5 c. vapor leaving the flash chamber has a quality of 0.97 and the temperature in the condenser is 32 c. for 350 kw of refrigeration. a) how much chilled water at 5 deg C does this system provide b) how much make up water is needed c) how much vapor must the system ejector remove from the flash chamber answers: a) 10.41 kg/s b) 0.1521 kg/s c) 21.7 kg/sThe condensing pressure for a Rankine engine is 0.001325 MPavac. Calculate the following for steam flow rate = 16.3846 kg/sec of steam when the steam at the beginning of expansion is at 119.6 deg SH and 4.0 Mpaa. Draw the TS and equipment diagrams for the ideal and actual case and find for the following for the ideal case: Combined work (KW) . Ans.____________________________ Combined steam rate in kg/KW-hr. Ans.___________________________ Actual heat rate( KJ/KW-hr). Ans.____________________________This is Problem 13 of Chapter 3 in Sustainable Energy by Richard Dunlap, 2nd Edition. I need help solving it: A coal-fired generating station has an efficiency of 38% and produces an average electrical output of 1000 MWe.(a) How much coal does it burn per second (kg/s)? Assume the coal is bituminous.(b) How much heat (in joules) is released to the environment per second?(c) How many liters of water at 20°C could the heat in part (b) boil (at STP) per second? For c, here is my idea: use Q = mc(change in T). Here change in T is (100 C - 20 C) or 80 C and c = 4200 J/(kg C) so I can solve for m. Question: I need the density of water to find liters, but density changes with temperature. So, do I use the regular 1000 kg/m^3 or something else?
