1. lower power consumption per unit of air delivered
2. higher volumetric efficiency
3. decreased discharge temperature
4. all of the above
all of the above
1. better lubrication is possible advantages of multistage
2. more loss of air due to leakage past the cylinder
3. mechanical balance is better
4. air can be cooled perfectly in between
more loss of air due to leakage past the cylinder
1. increase
2. decrease
3. remain unaffected
4. may increase/decrease depending on compressor clearance
decrease
1. slip factor
2. velocity factor
3. velocity coefficient
4. blade effectiveness
slip factor
1. up thrust
2. buoyancy
3. center of pressure
4. all the above are correct
buoyancy
1. the meta-center should lie above the center of gravity
2. the center of buoyancy and the center of gravity must lie on the same vertical line
3. a righting couple should be formed
4. all the above are correct
all the above are correct
