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...
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.Go To Calculator Newsletter...
the lowest wall pressure coefficient of plug is smaller than that of orifice plate at the same contraction ratio, and the energy loss coefficient of orifice plate is bigger than that of plug, which illustrates that plug is superior to orifice plate in resistance cavitation damage at the same co...

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 ...
Orifice width The width of the rectangular slot. The default value is1e-2m. Flow discharge coefficient Semi-empirical parameter for orifice capacity characterization. Its value depends on the geometrical properties of the orifice, and usually is provided in textbooks or manufacturer data sheets. The...
Piston orientation—Piston direction of movement Acts in positive direction(default) |Acts in negative direction Fixed orifice Fixed orifice area—Cross-sectional open area 1e-6m^2 (default) Fixed orifice flow discharge coefficient—Discharge coefficient for fixed orifice ...
The thermal expansion coefficient of cement paste is 10− 5/°C [29], so the strain exerted by the pore pressure is 2.5 × 10− 5/°C, and the magnitude of the pore pressure is PL = − (2.5 × 10− 5)(3)(6.7 × 109)/0.75 = − 0.7 MPa/°C. The discrepancy between...
The value of the pressure loss coefficient, to account for pressure loss in the return line. This parameter must be greater than zero. The default value is1. For reasons of computational robustness, the loss is computed with the equation similar to that used in the Fixed Orifice block: ...
A-29). Two types of elbow are considered: smoothly curved (standard) and sharp-edged (miter). The block covers elbows in the 5–100 mm and 0–90 degrees range. The block is based on the Local Resistance block. It computes the pressure loss coefficient and passes its value, as well ...
