This calculator is useful for very small piping or tubing, and can handle flow through small channels. It includes inlet and outlet losses, but cannot accommodate losses due to fitting and › HOME › REFERENCE LIBRARY.

Computers gathered data by reading pressure values from manometers placed in the wind tunnel. Depending on the application, the data were smoothed, plotted, and interpolated. Data reduction and analysis were carried out with the help of calculators, slide rules, planimeters, drafting tools, and other :// The term pressure loss or pressure drop is often used, this refers to the decrease in pressure in the system due to friction. In a pipe or tube that is at the same level, your garden hose for example, the pressure is high at the tap and zero at the hose outlet, this decrease in pressure is due to friction and is the pressure

Further pressure drop and pressure decrease on the outlet will not be felt upstream because the pressure wave can only travel as sonic velocity and the "information" about pressure drop will never translate upstream. Shock waves will occur but actual gas weight flow rate will not :// Select nominal pipe diameter (inches) using the pull-down menu.

Miller, R. A method for calculating mine ventilation pressure losses using computers and desk-top calculators: a supplement to Information Circular Hazen and Williams created an empirical formula to calculate pressure losses for liquids flowing through straight pipes. The formula below can calculate these losses over a given length of pipe.

L = length of pipe (m). d = inside diameter of pipe (mm). p = initial pressure - gauge (kg/cm 2). 1 kg/cm 2 = Pa = bar = atmosphere = mm Hg = mm H During wind tunnel tests, manometer boards measured pressure changes using liquid-filled tubes.

Computers “read” photographic films of the manometer readings, and recorded the data on worksheets.
