A garden hose attached with a nozzle is used to fill a 20-gal bucket. The inner diameter of the hose is 1 in, and it reduces to 0.4 in at the nozzle exit. The average velocity in the hose is 5.6 ft/s. Determine:

a. The volume and mass flow rates of water through the hose.
b. How long it will take to fill the bucket with water.
c. The average velocity of water at the nozzle exit.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

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
