A turbine operates on superheated steam that enters at 80 bar absolute and 500˚C, and leaves the turbine at 7.5 bar absolute and

250˚C. The flow rate of the steam is 400 kg/min and the turbine operates adiabatically. The steam exiting the turbine goes to a heater, which is supplied with 2000
2kW of energy. The steam leaves the heater at 5 bar absolute. All of the pipes through which the

steam flows are 0.5 m (id) in diameter.

a. How much power is produced by the turbine? (4 marks)

b. What is the temperature of the steam leaving the heater? (4 marks)

c. What is the velocity (m/s) of the steam entering the turbine? (3 marks)

d. To what temperature can the steam at 80 bar be cooled before a liquid will appear?

It is winter where jenna lives. Its been snowing all day, but now the snow has changed to sleet and then to freezing rain. What
Vladimir79 [104]

Hi!

Answer:

The change in temperature.

Explanation:

Snow forms at 0 °C, when water vapor converts directly into solid ice crystals. Sleet forms when raindrops fall through a layer of air colder than 0 °C. This means that from the time it was snowing to the time it started sleeting the air has gotten warmer but one layer of air stayed cold, hence the formation of sleet. Freezing rain is rain that freezes when it hits a cold surface. This means that from the time it was sleeting to the time there was freezing rain the air had completely warmed and is now above 0 °C but the ground and all other surfaces are still cold.

I hope this helps, as this happens all the time where I live! :)

The amount of substance present in a certain object with a given half-life in terms of h can be expressed through the equation,

     A(t) = (A(o))(0.5)^(t/h)

where A(t) is the amount of substance after t years and A(o) is the original amount. In this item we are given that A(t)/A(o) is equal to 0.89. Substituting the known values,

     0.89 = (0.5)(t / 5730 years)

The value of t from the equation is 963.34 years.

<em>Answer: 963 years</em>
