The calculator uses a pressure drop equation for isothermal flow. To calculate the pressure drop, the calculator performs friction factor f and minor resistance coefficient K calculation, as well as the mean velocity of the flow on the pipe start and the pipe end. The calculator includes Reynol...
The calculator also presents actual flow mean velocity in the pipeline for the specified pipe diameter. When is this calculator not relevant? The calculator is not suitable for situations where changes in pressure are extreme and sudden leading to adiabatic flow conditions. Download calculator Get...
简介 A simple, easy to use external ballistics calculator. It accepts inputs of bullet weight, ballistic coefficient, muzzle velocity, sight height, zero range, wind speed & angle, etc and calculates velocity, energy, flight path, and drift. ...
Pressure drop = Lamda * pipe length / hydr. diameter * density / 2 * velocity² As example acalculation of a rectangular pipe: Known: Width = 100 mm; Height = 50 mm; Length = 1 m Pipe roughness k = 0.1 mm Volume flow = 100 m³/h ...
Hazen-Williams formula: V = k C R0.63S0.54 Where: Full flow circular pipes Hazen-Williams R = D / 4 By Continuity Q = V A V = fluid velocity, m/s (ft/s), C = factor for relative roughnessHazen-Williams coefficient R = hydraulic pipe radius, m(ft), ...
No matter how fast it’s going when it reaches the lower layers of the atmosphere, it quickly slows down to terminal velocity. It always takes six or seven minutes to drop from 25 kilometers to the ground. For much of those 25 kilometers, the air temperature is below freezing—which ...
