A water-filled manometer is used to measure the pressure in an air-filled tank. One leg of the manometer is open to atmosphere.

ddd [48]

Answer:

$P = 150.335\,kPa$ (Option B)

Explanation:

The absolute pressure of the air-filled tank is:

$P = 101.3\,kPa + \left(1000\,\frac{kg}{m^{3}} \right)\cdot \left(9.807\,\frac{kg}{m^{3}} \right)\cdot (5\,m)\cdot \left(\frac{1\,kPa}{1000\,Pa} \right)$

$P = 150.335\,kPa$

Nitrogen at an initial state of 300 K,150 kPa and 0.2 m3is compressed slowly in an isothermal process to a final pressure of 800

Dmitry_Shevchenko [17]

Answer:

-50.22kJ

Explanation:

Given:

Initial state Temperature =300k

Pressure 1= 150kPa

Pressure 2 = 800kPa

Volume 1 = 0.2m^3

Work done = Pressure 1 × Volume 1 × (inverse of pressure 1 ÷ pressure 2)

= 150kPa × 0.2m^3 × (inv 150 kPa ÷800 kPa)

= - 50.22kJ
