Chapter 37, Problem 1RQ
Name five changes that are made to air to condition it.
Expert Solution & Answer
To determine
The five changes made to air for its conditioning.
Answer to Problem 1RQ
The five changes made to air for its conditioning is heating, cooling, humidifying, dehumidifying and cleaning.
Explanation of Solution
The atmospheric air contains a lot of impurities which can harm the human body in many ways. The normal atmospheric air contains moisture, odor, poisonous gases as well as dust particles, etc. Air conditioning is the process to remove these impurities from the air and make it clean to comfort the human body.
To clean air for conditioning it is necessary to make some changes. The major five changes that are required to make in the air for conditioning are listed below:
- Heating:
Atmospheric air is heated to higher temperatures to kill the bacteria and germs present in it.
- Cooling:
Heated air then cooled so that it can be adequate for human comfort.
- Humidifying:
Air is humidified to add some moisture in it.
- Dehumidifying:
Air is dehumidified to remove the excess moisture from it.
- Cleaning:
Cleaning of air includes removing any smell, bacteria and dust particles present in it.
Conclusion:
Thus, the five changes made to air for its conditioning is heating, cooling, humidifying, dehumidifying and cleaning.

2 A metal block of mass m = 10 kg is sliding along a frictionless surface with an initial speed
Vo, as indicated below. The block then slides above an electromagnetic brake that applies a
force FEB to the block, opposing its motion. The magnitude of the electromagnetic force

Q1: Determine the length, angle of contact, and width of a 9.75 mm thick
leather belt required to transmit 15 kW from a motor running at 900 r.p.m. The
diameter of the driving pulley of the motor is 300 mm. The driven pulley runs at
300 r.p.m. and the distance between the centers of two pulleys is 3 meters. The
density of the leather is 1000 kg/m³. The maximum allowable stress in the
leather is 2.5 MPa. The coefficient of friction between the leather and pulley is
0.3. Assume open belt drive.
5. A 15 kW and 1200 r.p.m. motor drives a compressor at 300 r.p.m. through a pair of spur gears having
20° stub teeth. The centre to centre distance between the shafts is 400 mm. The motor pinion is made
of forged steel having an allowable static stress as 210 MPa, while the gear is made of cast steel
having allowable static stress as 140 MPa. Assuming that the drive operates 8 to 10 hours per day
under light shock conditions, find from the standpoint of strength,
1. Module; 2. Face width and 3. Number of teeth and pitch circle diameter of each gear.
Check the gears thus designed from the consideration of wear. The surface endurance limit may be
taken as 700 MPa. [Ans. m = 6 mm; b= 60 mm; Tp=24; T=96; Dp = 144mm; DG = 576 mm]
