What is the maximum suction lift of a solid column of water?
I must assume you mean uniterrupted column of water! The maximum suction lift of a column of water is the height of a column of water (inside a vertical pipe for instance) that can be supported by atmospheric pressure i.e. approx 14.69psi or 760mm Mercury. You should be aware that suction does not cause water to lift. Suction produced by various kinds of pump merely removes air from above the column of water and this allows atmospheric pressure to act upon the base of the water column. The water column is therefore pushed upwards by atmospheric pressure from below rather than pulled up by suction from above. The density, vapour pressure and surface tension of water vary slightly with temperature and atmospheric pressure also varies slightly with weather conditions. Thus the measured height of the water column may vary slightly according to the conditions prevailing when making the measurement. A good approximation at room temperature is 33 feet or 10 metres.

What does the head pressure do if the suction pressure rise?
the head pressure will rise
What causes high exhaust temperature in marine engine?
Engine overload, insufficient scavenge air (ensure blower suction filters are not clogged), also ensure no air leakage between the blower and scavenger, expanded injection nozzles, damaged or worn valves or valve seat.
Why does a tornado sometimes damage one house and not the other house next to it?
Some tornadoes, called multiple vortex or multivortex tornadoes, have smaller suction vortices, sort of mini-twisters, moving around in side of them. These suction vortices have stronger winds and can sometimes do much worse damage than the winds in the rest of the tornado. Sometimes these vortices are only a few yards wide.
Would you recommend a suction filtration for a solution in which ether is the solvent?
no because it has a low boiling point so will evaporate in vacuum and dissolve the solid clogging the filter paper
How do you determine what suction pressure should be in R22 air conditioning compressors suction line?
The proper suction pressure of any air conditioning or refrigeration system is determined by the type of refrigerant used and sometimes the amount of charge. : Suction pressure used is also directly related to the temperature required. : The temperature required in the evaporator relates to the pressure required in the suction line since, the fluid is at saturation in the evaporator. : Knowing the temperature required, use the fluid's saturation tables to find the corresponding pressure required.
Which port do i Add refrigerant to dodge Dakota?
To add refrigerant to a Dodge Dakota find the suction hose of the A/C system. On the suction hose locate the port to add more refrigerant to the system.
To maintain 40 degree evaporator coil temperature what is the suction pressure?
It depends on the refrigerant you are using, for R-22 it's 72 psi
What is the property of refrigerant 404A?
what is suction pressure of r407a
Is suction pressure another word for evaporator saturation pressure?
Yes
Refrigerant entering a compressor of a refigerant system is?
Suction gas
Does refrigerant enter the compressor as a low temperature low pressure gas?
Yes. The basic components of the refrigeration system are the refrigerant, compressor, condenser and receiver, expansion device and the evaporator. One cycle: Refrigerant travels to Compressor (A) to Condenser (B) to Expansion device (C) to evaporator (D). The refrigerant gas at low pressure and temperature is drawn into the compressor. The gas is compressed to a higher pressure, which causes an increase in the temperature. The refrigerant gas at a high pressure and temperature passes to the condenser (point B), where it is cooled (the refrigerant gives up its latent heat) and then condenses to a liquid. The high pressure, low temperature liquid is collected in the receiver. The high pressure liquid is routed through an expansion valve (point C), where it undergoes an abrupt reduction in pressure. That pressure reduction causes part of the liquid to immediately vaporize or flash. The vapor and remaining liquid are cooled to the saturation temperature (boiling point) of the liquid at the reduced pressure. At this point most of the refrigerant is a liquid. The boiling point of the liquid is low, due to the low pressure. When the liquid refrigerant enters the evaporator (point D), it absorbs heat from the process and boils. The refrigerant gas is now at low pressure and temperature, and enters the suction side of the compressor, completing the cycle.
What should the low pressure be on a hvac system?
The pressure should be equal to a saturated suction temperature of around 40*F. The pressure would differ depending on which refrigerant is used.
How much 404 refrigerant does a walk in freezer take on new install?

How do you know which port to put in refrigerant in a car?
it usually has a blue cap on the suction port.
What is the correct suction pressure whin charging a chiller using refrigerant 134a?
926.5
What is the purpose of the external equalizer on a TXV?
The purpose of the External equalizer on the TXV is to compensate for the pressure drop in the evaporator coil , This is done since the superheat calculation is based on the difference in the Saturation temperature corresponding to the Suction pressure (Measured after the coil) and the actual suction line temperature. Now, in a TXV measurement of actual line temperature is accomplished by using the Sensing Bulb and the Measurement of the Suction pressure by the External Equalizer of the TXV. The opening/Closing of the Expansion valve is controlled by the setting of the superheat which is governed by the setting of the Spring.
