Asmall ideal two-stroke, single cylinder model otto engine has a compression ratio of 5: 1. the intake air is at 14.7 psi and 80°f. the cylinder has a 0.75 in bore and the piston has a 1 in stroke. if the highest cycle temperature is 700°f, determine the net power ouput of this engine in [ftlbm/s] when it is running at 800 rpm.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
