How do you calculate suction pressure for air theoretically?
Air has a pressure, but not a suction pressure. Air pressure is measured with a barometer, you do not calculate it. Suction pressure is a concept which applies to a pump. Suction pressure = static pressure + surface pressure - vapour pressure - friction pressure.
What is the fan speed relationship to suction pressure?
for a given air conditioner: the faster the condenser (outdoor) fan the lower the suction pressure. the faster the evaporator (indoor) fan the higher the suction pressure.
What causes an air mass to have a high pressure?
Anti-cyclone
What are two processes to cause metamorphism?
what are the physical conditions that causes metamorphism?
Why would your air conditioner have a normal to slightly high suction pressure and low head pressure with a 3 to 5 degree temperature difference?
What you're describing sounds suspiciously like a worn compressor.
What causes high head pressure and normal suction pressure in a air conditioner?
non condensebles in system dirty cond coil high ambient poss over charge
Is the suction line the high side?
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
What happening when you are overcharging an air conditioning with freon?
discharge pressure is high, suction pressure is high superheat is low and subcooling is high.
What is vapour binding?
when pressure on the suction side of the pump drop below the vapour pressure of the liquid, vapour forms. It's caused because of insufficient suction head, high suction lift, excessive friction head, or high liquid temperature.

A refrigerator with a freon restriction would have what symptoms?
High head pressure; low suction pressure; overheated compressor
How does a suction cup hold objects in place?
A suction Cup will trap air behind itself which causes a partial vacuum. The negative pressure of trapped air or water causes it to keep in contact with the surface it is against.
What causes low suction pressure?
Married too long? Bored wife? She doesn't fancy you anymore??
Where is suction and discharge s?
Answer: The terms suction and discharge are the terms refer to hydraulics. In hydraulics if the the liquid has to be lifted or pumped to the usage area the hydraulic pump will be used . This pump will have to functions that is first suction to lift the fluid and the discharge or delivery . The familiar words in pair are lift and discharge; suction and discharge. The specification of pump for these terms are suction head and discharge head.AnswerThe suction pressure refers to the pressure of the referigerant being "sucked" back into the compressor. The suction pressure is a critical variable in ensuring the accuracy of the refrigerant charge, along with the tepmerature of that line as well. The "superheat", or heat added to the vapor in that line can be monitored in this manner.You have not mention which suction pressure... Actually Where ever the suction is presented that pressure is called suction pressure.... and suction pressure in practical cases normally always less that atmospheric pressure and in case of delivery pressure it is oppositeSaying that suction pressure is " the pressure of the referigerant being "sucked" back into the compressor " is not accurate.Simply , the suction pressure of a pump is the absolute pressure of a fluid , measured at the inlet of the pump ( in your answer , the pump is the compressor , and the fluid is whatever refrigerant. )The discharge pressure , is the absolute pressure of the liquid measured at the outlet of the pump.Obviously, the discharge pressure is usually bigger than suction pressure.
Is suction pressure is high side or low side of refrigeration system?
Low side.
When an evaporater experiences a heat-load increase the suction pressure does what?
The suction pressure increase.
What causes increases in barometric pressures?
Low and high pressure systems. Obviously if you have a Low pressure system the barometric pressure will get low. High pressure causes the barometric pressure to rise.
