Hello, How to evaluate pressure drop on pump system because of strainer and piping friction? Thank you

Hello, For combine pump like Feedwater pumps(HP/IP), NPSH value for HP and IP refers to different values. For instance when NPSH for HP is 7,9 , IP is 8,9. Suction point is the identical for HP and IP. What is the reason? Thanks

Hello, It can be said generally; when NPSH decrease, HEAD increase and EFFICIENCY increase or that case could be changed accordingly Thank you

Hello, What is the mean of High pressure blowing case and Intermediate Pressure blowing case? Clearly I would like to learn what is the point of blow case? Thanks

Hello, I would like to ask that potable water affects to galvanized piping negatively. If yes, what is the reason. Which material in galvanized pipe is affected by potable water? Thanks

Hello, Balance piston and Balance Drum is different or not. Thanks

Hello, Head* (1,1)^2 = max head I realize 1.1 is about the frequency. But I could not get totally what for is above formula used? Thank you

Hello; I would like to ask that you know any material comparison resource. I need to compare some metal material. Such as; A743 CA6NM vs A743 Gr. CA-15 AlSl 420 vs A182 F6a Class 3 etc. Thank you

Hello; In Centrifugal Pump,what is the purpose of balance piston or it must be used Thanks

Hello; Minimum flow value increases or decreases, which one is the more avail of process??? Thanks..

Hello; Why NPSH value should be less than reel value. For instance pumps datasheet normal NPSH is shown 7 meter besides "NPSH required must be less than 50% of NPSH available" is noted. What is the reason?? Thank you...

Hello; Minimum continious flow (MCF) is just for centrifugal pumps, Why does not positive displacement pump operate under this princible? Is there any another reason except design difference? Thanks
