In calculating the exchange of gases in internal combustion engines we employ a number of experimental coefficients and the choice for the values of these coefficients depends in considerable measure on matching the theoretical data to the experiment. One such coefficient is the flow-rate factor #ex...
The coefficient of absolute viscosity, when divided by the density of the liquid is called the kinematic viscosity. In the metric system, the unit of viscosity is called the stoke and it has the units of centimeters squared per second. One one-hundredth of a stoke is a centistoke. The ...
Hydraulic motors: Calculate displacement, input flow, shaft output power and its nominal speed. Valves: Calculate discharge coefficient of an orifice based on the flow rate, internal diameter, fluid density, diameter ratio and differential pressure. ...

In a small opening, the flow coefficient fitting formula is based on the exponential function and supplements the formula according to the leakage flow law of the valve spool [8,9,10]. The formula has a good fitting effect on the curve measured by Merritt; however, the calculated flow coeff...

Feng and Yang [33] investigated the hydraulic impedance of a surge tank located upstream and downstream to a turbine in the system. They found an inverse relation between the hydraulic resistance coefficient of the surge tank and attenuation factors of the system; however, the influence of ...
where Cd is the orifice flow coefficient of the throttle valve, AT is the orifice area of the throttle valve, ρ is the density of oil, p1 is the inlet pressure of the throttle valve, and p2 is the outlet pressure of the throttle valve. In accordance with Equation (5), the input/out...
