    (iii) When parallel slide valves are used as stop valves, these can be fitted equal in size to the reducing valve for reduced pressures between 30 and 70% of the inlet pressure. They should be equal in size to the respective pipe when the pressure difference between the inlet and outlet is 2 bar (30 lbf/in2) or less.

  • How do heat exchangers work? - Explain that Stuff

    Heat exchangers have lots of other familiar uses too. Engines in cars, ships, and planes use heat exchangers to work more efficiently, and if you have a refrigerator or an air-conditioner in your home, those are using heat exchangers too. So what exactly are heat exchangers and how do they work?
