Determine the entropy production rate for the value
R-22, flowing steadily at 70 lbm/hr, enters the expansion valve of a refrigeration system as a saturated liquid at 183.09 psia. At the exit of the valve, the pressure is 31.162 psia. Determine the entropy production rate (Btu/hr-R) for the valve.

Formic acid has molar mass of 46.03 g/mol and is composed of 26.1%C, 4.38% H and 69.52% O by mass. What is the molecular formula for this substance (list elements in the formula in the same order as given in the problem statement)?
The coefficient of kinetic friction between the two blocks is 0.300, and the surface on which the 8.00 kg block rests is frictionless. A constant horizontal force of magnitude F=10.0 N is applied to the 2.00 kg block, setting it in motion.
