An air-standard otto cycle has a compression ratio of 6 and the temperature and pressure at the beginning of the compression process are 5208r and 14.2 lbf/in.2, respectively. the heat addition per unit mass of air is 600 btu/lb. determine (a) the maximum temperature, in 8r. (b) the maximum pressure, in lbf/in.2 (c) the thermal efficiency. (d) the mean effective pressure, in lbf/in.2

What precautions should you take to prevent injuries when dealing with heavy loads?

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk

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.
