It is the difference between the saturation temperature corresponding to the steam inlet pressure of feed water heater and it's outlet temperature.
Both temperatures are related to the saturation temperature in the steam drum of a heat recovery steam generator. The approach temperature is the water temperature at the economizer outlet, which in many analyses is assumed to be equal to the saturation temperature for simplicity. The "pinch point temperature difference" is the difference between the saturation temperature and the gas temperature at the economizer inlet.
Hot Approach: It is difference in temperature of hot fluid inlet temperature and cold fluid outlet temperature Cold Approach: It is difference in temperature of Hot fluid outlet temperature and cold fluid inlet temperature. Mohsin
The Approach is the difference between wet bulb temperature and outlet water temperature from cooling tower. That means , in this case, Approach = 35-25=10 degrees.
For efficiency's sake, the outlet had best be a lot cooler.
2 Amp
it is the pressure difference between inlet and outlet of pump.
"head" is where it starts, the mouth is the outlet.
Which direction the tub outlet is in relation to the apron
as intake air temperature increases it lead to decreas in i.c engine efficiency. as engine efficiency is ratio of difference in intake and outlet temperature to intake temperature.
Cigarette lighter outlet is special outlet that will hold and power a cigarette lighter. A power outlet is designed so a cigarette lighter won't work with it. They look the same and most 12 volt car accessories will work in either.
An extension cord is a long power cord that plugs into an outlet and receives with an outlet. A computer cord just uses one long cable to transfer power to the computer from the outlet.
