WebConsequently, the safety valve would be sized to pass at least 953 kg/h when set at 4 bar g. Once the fault load has been determined, it is usually sufficient to size the safety valve using the manufacturer’s capacity charts. A typical example of a … Webtions occur at low °ow rates and in the °ow of high-viscosity polymers. Situations in which viscous efiects are relatively unimportant will be discussed in Chapter 7. Solution procedure. The general procedure for solving each problem in-volves the following steps: 1. Make reasonable simplifying assumptions. Almost all of the cases treated
