The ratio inlet to throat diameter vary from 1/3 to 3/4,but the most suitable is from 1/2 to 1/3
It is pretty low, close to zero.
An obstruction (orifice) is placed in a pipe filled with fluid. The pressure of the fluid is measured at two different points: 1) just upstream of the orifice and, 2) close to the contraction of the fluid (vena contracta). The difference in these two pressures is known as differential pressure. The differential pressure across an obstruction (orifice) in a pipe of fluid is proportional to the square of the velocity of the fluid. Many factors associated with the pipe, orifice and fluid affect the measurement. Satisfactory measurement requires steady-state, homogeneous, turbulent flowing fluids. Other properties which affect the measurement include: the ratio of pipe diameter to orifice diameter and the density, temperature, compressibility and viscosity of the fluid.
Pewter or bronze depending on the ratio of the copper to tin.
You can change the air-to-fuel ratio to get less optimal combustion.
The boilup ratio will help determine the bottom operating line of your column. Once you have both your bottom and top operating lines you can step off the number of stages (given the desired compositions at the top and bottom of your column).
Ratio of the cross-sectional area for gas flow at the nozzle inlet to that at the throat.
blow ratio is the ratio of mold diameter to the preform diameter.
That ratio is about 53,000.
