Blower delivery calculation 04/14/2008 11:26 AM iamhaving a blower which is fitted with 7,5 hp motor 550 mm impeller 50 mm thik 8 blades welded on the impeller running at 2880 rpm what is the CFM 1 want to modify the blower to 3500 cfm what should i do
Re: Online bidding for manufacturing work. 10/29/2006 1:47 AM. the system works, although you may not greatly benefit from it, if you are not located in a country that makes you competitive. this is a global system, and you'll be competing with people from all over the world, like Malaysia, where we are, Hong Kong, Taiwan, China, etc.....
A better insulin-delivery for diabetics. Insulin is an essential hormone produced by the pancreas that helps the body turn food into energy and control blood sugar levels. For diabetes patients, the body doesn’t produce enough insulin and/or it doesn’t use the insulin correctly.

Re: stratopower hydraulic pump. The pistons are arranged in parallel with each other in a circular array. The bottom of each piston terminates with a ball. The balls are gripped by sockets in a rotating "swash plate." This plate can be tilted at various angles; if perpendicular to the axis, no piston movement occurs.
Fans are used for delivery pressure less than 0.5 lb/in2 (3.447 kPa) , compressor are used to increase pressure upto several hundred kPa (lb/in2 ). Blower comes in-between pressure range of fans & blower.
Now assume all the calculations are based on actual conditions. (Since I am not at 68 F, 36% RH and 14.7 PSIA conditions) Computing Compressor air delivery based on pump up time is a fairly easy computation. CFM = (final tank press-intial tank press) x V (tank size in gal.)/7.48 x atmos. press (psia) x time (in mins.).
Good Answers: 5. # 11. Re: Pressure in parallel pipes. 06/19/2008 2:28 AM. In a static condition, no flow, the pressure will be the same at all places. If all sprinklers are open and flowing the 3" diameter pipe has less area than 3, 2" pipes. The closest 2" will get the lions share of flow and highest pressure.
Data :- Atlas copco 55KW/ Screw type /Free air delivery 165 litres per scond/ 1000 litres of air accumulator for maximum pressure 7 Bar/ the compressor is set to operate start at 5.6 bar & stop at 6.5 bar./ The compressor shows utiliastion 3138 Hrs of loading & 13300 hrs running.
