Two airstreams are mixed steadily and adiabatically. The first stream enters at 35°C and 30 percent relative humidity at a rate of 15 m3/min, while the second stream enters at 12°C and 90 percent relative humidity at a rate of 25 m3/min. Assuming that the mixing process occurs at a pressure of 90 kPa, determine the specific humidity, the relative humidity, the dry-bulb temperature, and the volume flow rate of the mixture. Use data from the tables.

a) The specific humidity is __kg H2O/kg dry air.

b) The relative humidity is __ %.

c) The dry-bulb temperature is __ °C.

d) The volume flow rate of the mixture is __m3/min.

A square-thread power screw has a major diameter of 32 mm and a pitch of 4 mm with single threads, and it is used to raise a load putting a force of 6.5 kN on the screw. The coefficient of friction for both the collar and screw is. 08. If the torque from the motored used to raise the load is limited to 26 N*m, what is the largest value that the mean diameter of the collar can be?

A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 125 kPa. Initially, 2 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 20 percent.

Determine:

(a) the initial and final temperatures,

(b) the mass of liquid water when the piston first start moving
