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 ... Webdenotes the distance above the boundary. The fluid velocity at the boundary (y = 0) is zero. At some distance above the boundary the velocity reaches a constant value, U∞, called the free stream velocity. Between the bed and the free stream the velocity varies over the vertical coordinate. The spatial variation of velocity is called shear. WebApr 6, 2024 · We expect the pressure drop to be 1 over (⅔)^4.9 or about 7 times higher than the original pipe. At 0.3 gpm, the pressure drop is 3 inches. That’s about 6 times the original. At 0.6 gpm, the pressure drop is 7.5 inches, about 7 times the original. And at 0.9 gpm, we’re off the scale. p rtl
