How to choose motor size when the blower wheel material differs. It is centrifugal fan DIDW Double Inlet. Existing blower fan is made from aluminium material (67kg including shaft) which later replaced with blower fan made from mild steel material (93kg including shaft. Now how to determine the horsepower of the motor since new blower wheel will be heavier. Everything else remain same except the blower wheel weight.

Sir i have 29 hp d engine 2200 rpm with 6 inch pulley. Tell me water fan pulley size? Because i have 8 inch water fan pulley. In this position tube well water though is best but engine on some fast speed?

PS - what about calculating the ratio of motor and fan pulleys to achieve a desired CFM. Also, how to calculate existing CFM if not stated.

If i have a 1440 RPM motor and i want 1000 RPM in my machine. So how can i reduce motor RPM?
Describe with formula please

Thought this was how to calculate fan displacement. You already know the displacement, this is just calculating a new ratio.

Fantastic video, maybe you could do a video on duct pressure loss calculations which ties up to fan selection. great job

I have a question, what's happen if diameter of fan pulley doesn't match with diameter of pulley motor? Thanks before

How are you measuring the pulley diameter? Bottom of the groove, the edge or with the belt on the pulleys?

Does fan size (the diameter of the propeller) affect the airflows? How these variables correlate at each other?
