The pump has an impeller diameter of 380 mm and when operating discharges 310 m3/h of water while producing a hydraulic head of 45 m. The power requirement is 55 kW. Determine the required impeller diameter of a geometrically and dynamically similar type of pump that must deliver a discharge of 280 m3/h and produce its head. What is the power requirement for this pump
Dimension of width (b) is taken with respect to diameter (d). First diameter is decided then after from diameter width (b) is decide.hence b is proportional to d.
Keep working, friend, God will surely give you the fruits of your hard work one day.
Thank you for comment.
Tomorrow I am having exam on this topic bro, derivation part was so good and clean thanks for clearing my subject doubts 👏👏

How to calculate pump efficiency on specific speed of pump
The pump has an impeller diameter of 380 mm and when operating discharges 310 m3/h of water while producing a hydraulic head of 45 m. The power requirement is 55 kW. Determine the required impeller diameter of a geometrically and dynamically similar type of pump that must deliver a discharge of 280 m3/h and produce its head. What is the power requirement for this pump
Sol
How B is directly proportional to D
B dimension taken with respect to D. Example: B = 0.2 D, B = 0.4 D.
I still don't understand how B proportional to D...can u elaborate more ..plz
Dimension of width (b) is taken with respect to diameter (d).
First diameter is decided then after from diameter width (b) is decide.hence b is proportional to d.
Thank u...it's really helpful
