Operators now have increased awareness of reliability coefficient for pumps due to concern for environmental reasons. Operators have little tolerance for the...
Using EnggCyclopedia’s Liquid Density Calculator, water density at 250C =994.72 kg/m3
Using water density, the mass flow rate is converted to volumetric flow...
Δp : frictional pressure drop, Pa
D : internal diameter, m
L : Pipe length (or equivalent length), m
Ff: fanning factor
FD : Darcy factor
e :...
Spiral heat exchangers are very basic in their structure. They consist of two separate spiral chambers as shown in the schematic below. These two chambers...
Q = h×A×(T1 - T2)
where Q : heat transfer rate in Joules/hr
A : Effective heat transfer area of the solid surface in m2
T1 & T2 : Steady state...
