WebMay 17, 2024 · Fan Law 3: Horsepower changes with the cube of CFM (or RPM) Formula: HP2 = HP1 X (CFM2 ÷ CFM1)³. What it means: A 10% increase in airflow results in a 33% increase in horsepower required to do that work. If your motor is already close to its rated HP, a small airflow increase can overload it. Let’s demonstrate that.
WebQ = V t, 12.1. where V is the volume and t is the elapsed time. The SI unit for flow rate is m 3 /s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min). Note that a liter (L) is 1/1000 of a cubic meter or 1000 cubic centimeters ( 10 − 3 m 3 or ...

WebThis formula is used to calculate the air speed in the duct, and its actual value. All other missing data can be derived from the same formula. For example, to calculate the air flow, the formula must be transformed as follows: L = 3600 x F x ϑ. In some cases, such calculations are difficult or time consuming.
Web500 < NS < 4200 Centrifugal or Radial Flow. 4200 < NS < 9000 Mixed Flow. NS > 9000 Axial Flow. Influence of motor speed on pump performance: 1. Specific speed NS. N S = N Q 0.5 / H 0.75. Due to the above figure and the specific speed formula, if we need low flow and high head in some conditions, the following conditions will occur. flagged messages disappeared outlookWebFlow rate V ˙ 2 = V ˙ 1 ( n 2 n 1) = ( 400 gpm) ( 3600 rpm 1800 rpm) = 800 gpm Head H p .2 = H p .1 ( n 2 n 1) 2 = 48 ft ( 3600 rpm 1800 rpm) 2 = 192 ft Power P 2 = P 1 ( n 2 n 1) 3 = 45 kW ( 3600 rpm 1800 rpm) 3 = 360 … flagged league nameWebNov 26, 2024 · To calculate blood flow rate through a blood vessel: Divide the diameter of the vessel by 2 to obtain the radius.
