In the air conditioning process in the humidifier, air at a dry bulb temperature of 30 degrees C and RH of 10% increases its RH to 50%. Determine the amount of moisture added in the humidifier per kg of dry air: ....

Find the gas constant for N2 (nitrogen) in J/(kg .K)

Following the theorem of corresponding states, for compressibility factor Z> 1.0 (hard fluid) The fluid has mass, but its molecule have (or assumed to have) zero volume The molecules do not exert any force on the neighboring molecules (i.e., no attractive or repulsive forces). Repulsive forces are dominant between molecules and the neighboring molecules Attractive forces are do molecules bet ules and the neighboring

Given the following property data for H,0 designate the region in T-v or P-v space (i.e., compressed liquid, liquid-vapor mixture, superheated vapor, etc.) and find the value(s) of the requested property or properties. Use the tables in Appendix D or the NIST database as necessary. Provide units with your answers.

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.

Mr Zul operates a hot plate. He places a closed, rigid container of volume 0.5 m3on the hot plate. Initially, the container holds a saturated mixture with quality ofvapour of 0.5, at a pressure of 100 kPa. After heating, the pressure in the containerincreases to 150 kPa.a) Calculate the mass of vapour at the initial and final states (in kg).b) If heating is allowed to continue, find the pressure (in kPa) when thecontainer holds only saturated vapour.c) Sketch the T – v diagram for this system.
