Steam enters a turbine steadily at 7 mpa and ‘w 600c c with a velocity of 60 m/s and leaves at 25 kpa with a quality of 95 percent. a heat loss of 20 kj/kg occurs during the process. the inlet area of. the turbine is 150 cm2, and the exit area is 1400 cm2. determine (a) the mass flow rate of the steam, (b) the exit velocity, and (c) the power output.
complex. they both mean a machine which involves two or more simple machines.
in longitudinal waves, particles of the medium vibrate to and from in a direction parallel to the direction of energy transport. if energy is transmitted along a medium from the east end to the west end, then particles of the medium would vibrate eastward and westward
a sound wave is a longitudinal wave but not the answer since a wave which exhibits this characteristic is not necessarily a sound wave.
so the answer is 5
the acceleration is negative when the speed starts to decrease, which is confirmed by the second situation: b) the velocity of a car reduced from 50km/hr over one minute.
they both are heterogenous mixtures.
