Air with a dry bulb temperature of 22C and a relative humidity of 60 percent is contained in a frictionless-piston-cylinder assembly that has an initial volume of .5m^3. The air is expanded at a constant pressure of 1 atm until the dry bulb temperature reaches 35C. During this process heat is transferred to the air from a reservoir having a temperature of 80C. Determine the amount of heat transferred to the air during the process (in kilojoules) and the work.
a carefully controlled tensile test is conducted on a metal alloy specimen. the original diameter is 10 mm and the gage
Calculate the change in internal energy of the gas. Remember it is an ideal gas in a constant temperature bath.
Determine the velocity ratios that can be achieved by the gear box in terms of number of teeth in the sun wheel and determine which component (out of the sun wheel, planet carrier and annular wheel) has to be used as the input shaft to get the req..
The roof is supported by cables. If the cables exert FAB = 100N and FAC = 120N on the wall hook at A, determine the magnitude of the resultant force acting at A.
temperature in state college pa on 31st december 2012 was 22 f. if the barometric pressure was 100 kpa and the humidity
A piston-cylinder device initially contains 50L of liquid water at 40 degrees C and 200kPa. Heat is transferred to the water at constant pressure until entire liquid is vaporized.
Computer programs and other software (including Web Pages like this one). This includes graphics and icons and the like, which may also be "graphic works". OK, my work is on the list. How do I copyright it?
Determine the heat transfer coefficient for laminar flow over this cylinder. First, at your discretion, select an available set of experimentally obtained data from the literature. Then, this would provide you with a set of Reynolds numbers.
determine the magnitude of its total accleration when (a) t=0 and (b) t=2 Whats the solution.
the truck at b is used to hoist the cabinet up to the fourth floor of a building using the rope and pulley arrangement.
a tank has a volume of 0.35m3 and initially contains saturated vapor at 333 kpa. the valve is next opened and steam
