Isobutane, air entering at 22 oC with a flow of 18 kg/s (cp = 1.0 kJ / kg.K)is condensed at 85 oC. The total heat transfer coefficient for this heat exchanger is 2400 W/m2.K and surface area is 2.6 m2. What is the output temperature of the air? Çeviri yap: Google Bing

Can you please help me with question 3
Please answer asap.. I will rate helpful thankyou
A compressor is used to increase air pressure with the assumption that there is no heat transfer from/to the compressor. The air is entering at 150 kPa and 37 C and leaving at 650 kPa and 227 C with 250 kg/min as mass rate. The constant-pressure specific heat of air is 1.011 k/kg, and the gas constant is 0.287 k/kg.K while the surrounding is 27"C and 100 kPa. a. Deterrmined the entropy charnges of air after the process. b. Determine the reversible power of the compressor in kW.

A factory uses superheated steam (P = 15 bar, T = 250 oC) for heating purposes of 20,000 tons/month. Steam is made in a boiler-furnace using 2 (two) types of fuel, namely coal fuel (LHV = 5500 kcal/kg) and heavy fuel oil (137129 Btu/ft3, density = 0.98 m3/kg) Question: a. How much coal fuel is needed to produce steam with the above specifications if the overall efficiency of the system (boiler-furnace = 75%)! b. How much heavy fuel oil is needed to produce steam with the above specifications (boiler-furnace = 75%)! answer every month... Help pleasee.. fast please
