What is the difference between back pressure steam turbine and condensate steam turbine?
In a back pressure turbine all available energy from the inlet steam is NOT used to generate power; steam exhausts at a tangible pressure and is then used for, usually, heating or chemical processing. In a condensing turbine, all the inlet steam does mechanical work right down to the lowest pressureafter which it is condensed in a heat exchanger
How do you calculate pressure ratio of compressor?
Inlet pressure/discharge pressure
What NPSH stands for and its meaning?
Net Positive Suction Head. It is the difference between hydraulic pressure and vapor pressure, usually of concern at the inlet of a pump. Without sufficienty high NPSH at a pump inlet, there will be cavitation in the pump. Within a centrifugal pump there can be pressures lower than at the inlet as the fluid is moved by the impeller. If any of those pressures is lower than the vapor pressure, vapor pockets- bubbles- form and you get cavitation. A more complete explanation: http://en.wikipedia.org/wiki/NPSH
What is an inlet valve?
Inlet Valve is comprised of 2 words i.e. Inlet & Valve. Therefore Inlet Valve is that valve through which fuel or a mixture whose pressure in increased by reducing its volume in intaked into the cylinder.
Where is the inlet and outlet of your pressure tank?
A pressure tank for a pump & well potable water system only has one connection. To connect the pump and tank to your house's water inlet, simply connect the tank and pump together with pressure rated pipe, SCH 40 PVC works fine. In that line, cut in a TEE fitting, and from that T, connect the house inlet with a valve to shut the water off.
What is flash separation?
A flash separator consists of a vessel where the pressure is lower than the inlet stream. When the inlet stream enters the tank (which has a larger volume), the pressure may drop, as well as the temperature. When the pressure drops, the vapors dissolved in the liquid inlet will boil, "flash," into the vapor phase. Thus, the dissolved gases in the liquid are separated by "flashing" them.

What makes a Compressor on and off all the time?
Hi the compressor has a device usually a pressure switch that on off loads the head inlet compression valve system. With a screw compressor it is usually a diaphragm operating a piston that open and closes the inlet to the element
What is the function of hydrogen in an absorption refrigerator?
usually hydrogen or helium gas were choose as inlet gas/ carrier from evaporator to absorber coil. Inlet gas contribution toward total pressure in the system where according to formula to determine partial pressure in the system PTOTAL SYSTEM = P HYDROGEN (inlet gas ) + P AMMONIA (REFRIGERANT )

For the same size of pipe when mass flow rate is also same what will happen to the pressure drop if change in inlet pressure takes place?
If you change the inlet pressure, you outlet pressure will also change dramatically.
What is unit of differential pressure?
Let me differentiate first between design pressure and mechanical design pressure. Design (or discharge) pressure is the pressure at the outlet of the pump, the pressure you've designed the pump to deliver. The mechanical design pressure is a value that the pump casing and downstream piping have to be able to withstand as a minimum*. I presume you mean design pressure as discharge pressure. In this case, differential pressure is the difference between the discharge pressure and the suction pressure (the pressure at the inlet of the pump**). * this is calculated taking into account that a pump would be working against a 'blocked discharge' or a closed valve in the outlet piping ** imagine a reservoir filled with liquid
What is up stream pressure?
The upstream pressure is the pressure in a pipe or duct on the inlet side of a piece of mechanical equipment.

Inlet Valve is comprised of 2 words i.e. Inlet & Valve. Therefore Inlet Valve is that valve through which fuel or a mixture whose pressure in increased by reducing its volume in intaked into the cylinder.
Where is the ac low pressure side switch on 4.3 Blazer?
It's not a switch. The high pressure runs from the compressor outlet to the orifice tube inlet, and the low pressure side runs from the orifice tube outlet to the compressor inlet.
