Histopathology shows dilated bile duct system at all levels and bile duct proliferation in response to back pressure.
32.
As the amount of soot trapped on the DPF increases, so does the back pressure in the exhaust system.
33.
"' Back pressure "'refers to pressure opposed to the desired flow of gases in confined places such as a pipe.
34.
Consequently, the net thrust of a rocket motor is equal to the gross thrust ( apart from static back pressure ).
35.
Eventually the back pressure will be low enough so that it is now equal to the pressure at the nozzle exit.
36.
Running the cycle too often while keeping the back pressure in the exhaust system low will result in high fuel consumption.
37.
Final, draft-proof the room so as to ensure that the room space provides a little back pressure to the wind forces.
38.
When the back pressure, p b, is lowered enough, the flow speed is Mach 1 at the throat, as in figure 1b.
39.
Sources of back pressure may be boilers, heat exchanging equipment, power washing equipment, fire sprinklers, or pumps in the water distribution system.
40.
The double check valve assembly is suitable for prevention of back pressure and back siphonage, but is not suitable for high hazard applications.
