V = flow rate Usage example Input data: Friction factor - -15; head loss - 474 ft; pipe diameter - 20 ft; flow rate - -15 ft / sec; gravitational acceleration - -8 ft / sec 2 Click "Calculate" to display the results. Output results: The length of the pipe is 44.94 feet. Not...
KDis the resistance coefficient (see Fig. 2). Both depend on the ratio of areas and the angle of divergence. The formulas to calculate this loss ignore the effects of friction inside the conical section. If the enlargement is very gradual, the effects of friction can become significant. There...
If we are asked to calculate the value of voltage with the value of current and resistance, then cover V in the triangle. Now, we are left with I and R or more precisely I × R. Therefore, we use the following formula to calculate the value of V: V = I × R Substituting the va...
The water pressure at the end of the hose is equivalent to the voltage or potential difference in an electric circuit. The water in the tank is equivalent to the electric charge. Now if we increase the amount of water in the tank then more pressure is developed at the end of the hose....
In the pithy formula: how to calculate the power factor can be seen from the active and reactive meters. The power factor can be calculated by calculating the electricity consumption of the current month. Some enterprises have no power factor meter, power meter or reactive compensation equipment ...
andviscosityof the fluid. Friction loss can be computed ashlas friction loss is nothing but the energy loss. This resistance is termed as pipe friction and is measured in meters head of the fluid. Many types of research have been carried out to establish various formulae to calculate this ...
