When an evaporater experiences a heat-load increase the suction pressure does what?
The suction pressure increase.
Is it true that liquids rise in a straw because of suction?
yes <><><><><> Actually, the pressure outside the straw presses the fluid up into the straw.
What is negative suction?
pressure
What will cause the suction pressure to rise?
head pressure
Why do suction cup stick to wet surfaces better than dry surfaces?
No. How well a suction cup sticks to a surface has to do with how will a seal can be formed on the surface. Rough surfaces will not form good seals compared to smooth surfaces which means that suction cups will not stick as well to rough surfaces as they do to smooth surfaces.
What is the superheat if the suction pressure is 60 psig and the suction line temperature is 40 degrees?
-5 something is wrong
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 will happen if air enters the inside of a suction cup?
The suction cup will lose its attachment, unless it has an additional adhesive. Suction cups attached to a surface are held there by the pressure of the outside air, which is higher than the pressure under the cup. The suction cup is trying to return to its uncompressed condition, and pulls away from the surface, reducing the pressure under it.
What are the causes of high suction pressure?
Suction is caused by an are of negative pressure.
How do you use the temperature pressure table when measuring suction pressure on your split system air conditioner?
i think you subtract the evaporator temp from the outside temp?
When an evaporater experiences a heat-load increase the suction pressure does what?
The suction pressure increase.
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 it true that liquids rise in a straw because of suction?
yes <><><><><> Actually, the pressure outside the straw presses the fluid up into the straw.
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 is negative suction?
pressure
What will cause the suction pressure to rise?
head pressure
Does low suction pressure have an effect on reciprocating compressors?
At very low suction pressure, the suction valves of reciprocating compressor will not work and there will be no gas in the cylinder during compression stroke, resulting some damage to the suction valves. If low suction pressure trip protection is not provided there can be some abnormal damage.
