On a cool day in April a scantily clothed runner is known to lose heat at a rate of 500 W because of con- vection to the surrounding air at Too = 10°C. The run- ner's skin remains dry and at a temperature of Ts = 30°C. Three months later, the runner is moving at the same speed, but the day is warm and humid with a temperature of Too = 30°C and a relative humidity of ¢oo = 60%. The runner is now drenched in sweat and has a uniform surface temperature of 35°C. Under both conditions constant air properties may be assumed with v = 1.6 X 10-5 m2/s, k = 0.026 W/m · K, Pr = 0.70, and DAB (water vapor-air) = 2.3 X 10-5 m2/s.
(a) What is the rate of water loss due to evaporation on the summer day?
(b) What is the total convective heat loss on the summer day?
a 0.2 m3 tank containing helium at bar and 22 c will be used to supply 4.5 moles per minute of helium at atmospheric
Design the toll in orthogonal plane, Reference plane, cutting plane and draw its isometric view. Assume suitable shank dimensions.
Calculate the Reynolds number, the Nusselt number, the convective heat transfer coecient (h), and the total heat transfer (Q_dot) for the following: 1g/s of water owing through a 2mm-diameter circular tube, 2cm long, with wall heat flux q'' = 100 W/c..
There is a process in which ball bearings made of plain carbon steel are rolling from an oven at a uniform temp of 870 degrees Celsius into a water bath where the water is at 37 degrees Celsius to quench them. A rubber conveyer belt then carries them..

Using the generalized compressibility chart, calculate the volume of 2.9 kgs of Argon at a pressure of 6.8 MPa and 158.6 K. Give your answer in cubic meters.
Air, initially at 220 kPa and 450 K undergoes a polytropic state change to 374 kPa and 495 K. What is the polytropic exponent of this process? Saturated water vapor is contained in a rigid container. Heat is then added until the pressure and temperat..
