Question

1. What should be the water line gage pressure in the ground floor of a building so that water can rise up in the fifth floor which is 15m high?

2. Determine the volume occupied by a 2kg steam at 500kPa, under the following conditions:

(a) pressure state

(b) pure vapor state

(c) 20% moisture content

(d) 20% dry

When P (kPa) = 500, T (°C) = 151.86, Vf (m³/kg) = 0.0019 and Vg (m³/kg) = 0.3749

 

3. An automobile tire contains a certain volume of air at 205kPa, and 20°C. The barometric pressure is 100kPa, if due to maintaining conditions the temperature of the air in the tire rises to 70°C, what will be the gage pressure? Assume that the air is an ideal gas and that the tire does not stretch.

3. An automobile tire contains a certain volume of air at 205 kPa, and 20°C. The barometric
pressure is 100 kPa,. If due to running conditions the temperature of the air in the tire rises
to 70°C, what will be the gage pressure? Assume that the air is an ideal gas and that the
tire does not stretch.
