Aheat exchanger (80 horizontal tubes, 2.44 m long with a 25mm od) is made available for steam raising. estimate how much saturated steam can be raised at the following pressures, using levy or mcadams where appropriate. 0) 0.6 mpa (i) 0.7 mpa (iii) 0.8 mpa the tube wall is kept at 180°c by its internal fluid, and water enters at its boiling point

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Ahe-xe mixture containing a 0.75 mole fraction of helium is used for cooling electronics in an avionics application. at a temperature of 300 k and atmospheric pressure, calculate the mass fraction of helium and the mass density, molar concentration and molecular weight of the mixture. if the cooling capacity is 10 l, what is the mass of the coolant?
