Energy Balance - Manifold Example

Mass and energy balance is performed on the heat exchanger shown in the figure above. The measured values and the results are listed in the table below. Notice that a manifold preserves specific energy from the input to the output flows.

Energy Balance - Manifold Example

Flow	Measurement	Tolerance	Reconciled Value
F1	M	100 lb	3 lb
H	2 btu/lb	0.5 btu/lb	0 btu/lb
P1	M	51 lb	1.5
H	\<not measured>	-	2 btu/lb
P2	M	52 lb	1.56
H	\<not measured>	-	2 btu/lb
