1.What is the difference between safety valve and relief
valve?
Answer Posted / shubhankar suman
1. Relief valve opening is directly proportional to the
pressure rise.
Safety valve opening will happen at after reaching the set
pressure.
2. Safety valve can be operated manually with use of easing
gear (as in boilers) whereas Relief valve can not.
3. Safety valve is set at 3% above the working pressure
Relief valve is set at 10% above working pressure.
4. Safety valve is used in a vapour or steam system, whereas
Relief valve can be used in Fluid or compressed air system.
5.Safety valve releases the vapour or steam in Atmosphere,
but Relief valve releases the fluid in such a way that it
circulates in the system (suction line). But in case of
Compressed Air, it releases it to atmosphere.

Describe transfer machines?
why we use kg/cm2 instead of kg/m2 as a unit of pressure. As we know kg is a MKS unit and cm is a CGS unit. So why we use combination of both(kg/cm2)while describing the pressure.
