Water flows in a smooth pipe of diameter 1 ft with a velocity of 10 ft/s. If the kinematic viscosity of the water is 1.21*10-5 ft2/s, the headloss due to friction over a pipe length of 1000 ft is most nearly:

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
