Steam enters an adiabatic turbine at 5 mpa, 650°c, and 80 m/s and leaves at 50 kpa, 150°c, and 140 m/s. if the power output of the turbine is 8 mw, determine
(a) the mass flow rate of the steam flowing through the turbine and
(b) the isentropic efficiency of the turbine.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

the answer is a for sure mark brainliest i had got this right on usatestprep
