CBE2124, Levicky 3 Differential balances: The terms in a differential material balance are expressed as rates; that is, rate of input ( moles/s, kg/s), rate of generation, rate of output, and rate of accumulation. Differential balances are applied to continuous processes. Integral balances: These usually apply to batch processes.. The terms in a batch mater

Further calculations of water volume in the gas involved calculation of the dry fraction or percentage of water in the gas stream. To make this calculation, the water vapor fraction when the gas is saturated with water vapor is needed. This value is determined using saturation tables and for 152 degrees F, the saturated fraction is or %.

Heat and mass balance is a document produced by process design engineers while designing a process plant. Sometimes heat and mass balance is not a separate document but appears alongside the Process Flow Diagram (PFD). A heat and mass balance sheet represents every process stream on the corresponding PFD in terms of the process conditions.
Get PriceMass balance Wikipedia
A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem ...
