Consider first water and then sae 10w lubricating oil flowing at 40 degree c in a 6 mm diameter tube. if the maximum reynolds number for laminar flow is 2300, determine the maximum flow rate possible and the corresponding pressure gradient, dp/dx, for each fluid while maintaining laminar flow (h_2o: 7.10 times 10^-6 m%3/s, -145 n/m^3)

An air compression refrigeration system is to have an air pressure of 100 psia in the brine tank and an allowable air temperature increase of 60°f for standard vapor compression cycle temperatures of 77 f entering the expansion cylinder and 14 f entering the compression cylinder, calculate the coefficient of performance a. 2.5 b 3.3 c. 4.0 d. 5.0
