A well-insulated turbine operating at steady state develops 23 mw of power for a steam flow rate of 40 kg/s. the steam enters at 360°c with a velocity of 35 m / s and exits as saturated vapor at 0.06 bar with a velocity of 120 m / s.

Two in-phase loudspeakers that emit sound with the same frequency are placed along a wall and are separated by a distance of 5.00 m. A person is standing 12.0 m away from the wall, equidistant from the loudspeakers. When the person moves 1.

Work = force x distance Power = work / time 745 watts = 1 hp A tow truck is hired to pull out a 2000 Kg Car from a 10 meter deep ditch straight up and place it on the level ground.

The wavelength of light is given by the velocity divided by the frequency. the velocity of blue light is 300,000,000 m/sec, and its frequency is 650,000,000,000,000 cycles per second.
