Water flows through a tee in a horizontal pipe system. the velocity in the stem of the tee is 15 ft/s, and the diameter is 12 ݅݊in. each branch is of 6 in diameter. if the pressure in the stem is 20 psi, calculate magnitude and direction of the force of the water on the tee if the flow rate in the branches are the same.

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
