Air enters a compressor at a pressure of 74.7 kPa and 287 K and leaves at 622 kPa and 579 K. The air flow rate is 50 kg/s. Calcu

late the shaft power input required to drive the compressor. Hint: The shaft power that goes into the compressor increases the total enthalpy of the air from the inlet to the exit, since there is no heat into the system.

In the lab, a container of saturated soil had a mass of 113.27 g before it was placed in the oven and100.06 g after the soil had
kipiarov [429]

Answer:

  • Moisture/ water content w = 26%
  • Void ratio , e =  0.73

Explanation:

  • Initial mass of saturated soil w1 = mass of soil - weight of container

                                                 = 113.27 g - 49.31 g = 63.96 g

  • Final mass of soil after oven w2 = mass of soil - weight of container

                                                  = 100.06 g - 49.31 g = 50.75

Moisture /water content, w =   \frac{w1-w2}{w2} = \frac{63.96-50.75}{50.75} = 0.26 = 26%

Void ratio =  water content X specific gravity of solid

                  = 0.26 X 2.80 =0.728
