In this post I want to share to you how to estimate pump efficiency. An equation was developed by Carl Branan, author of the Process Engineer’s Pocket Handbook. Pump efficiency can be estimated by using equation below:
Where:
Eff. = Pump percentage efficiency
F = Developed head (ft)
G = Flow (GPM) Read More
In previous post I shared how to estimate insulation thickness for both flat surface and cylindrical surface. In this post I want to share how to estimate optimum insulation thickness.
The total annual cost of insulation is the sum of the cost of heat energy lost and fixed cost. A plot of cost vs insulation thickness will determine the most economical insulation thickness. A dimensionless factor can be used to calculate insulation thickness, depending on the ratio of insulation thickness to pipe diameter in the following equation:
