Derive a formula for the bullet speedvin terms ofd, t, and a measured angleθbetween the position of the hole in the first disk and that of the hole in the second. if required, useπ, not its numeric equivalent. both of the holes lie at the same radial distance from the shaft.θmeasures the angular displacement between the two holes; for instance,θ=0means that the holes are in a line andθ=πmeans that when one hole is up, the other is down. assume that the bullet must travel through the set of disks within a single revolution.

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa. (0.757, 4.37 kw, 5.12, 6.18, 3.91 kw)
