3.116 two kg of oxygen fills the cylinder of a piston-cylinder assembly. The initial Volume and pressure are 2m^3 and 1 bar respectively. Heat transfer to the oxygen occurs at constant pressure until the volume is doubled. Determine the heat transfer in the process, in kJ, assuming the spoecific heat ratio is constant, k

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
