Pump efficiency have always been a problem to determine, especially when no pump information is available. Here is a small equation which can be used to estimate an approximate value without power measurement. I see this equation more useful for getting the flow information which is generally not available while head & power can be measured.The formula is useful to make decisions for improvements i...

Mist Eliminators or Demister Pads are very common & important things for process engineers but they are often neglected. Here is some input from my side theory as well as practical knowledge & gains from them. The importance of a demister pad comes from the efficiency of separation & its impact on either product recovery or the indirect impact on downstream processes. Usually later is m...

The pump performance or characteristic curve is often referred to as a water performance curve (see Figure 1). Water is naturally the fluid of choice for testing pumps because of its availability. The question is: can the water performance curve be used for other fluids? The answer is YES with care.The pump manufacturers will sometimes identify the unit of the total head axis as feet of water, or s...

Today I'll share a very useful sure shot energy saving method in cooling water pumping system. So let me start as usual from some initial questions which are necessary for estimating the amount of efforts required in proving the concept....

Waste Heat - Every process engineer is aware of this word. But do you know how much % of total energy requirement in your plant is going as waste heat?....Don't Know......It can be as high as 50%.....!!!!......Yes, it can be. So what is waste heat...Simply from language it is the heat wasted in the process. So it is not just flue gases...
