What is the formula for the density of a truncated cone?
Density = Mass/[(1/3*pi*h) * (R12 + R22 + R1*R2)] where h is the height of the frustum, and R1 and R2 are the radii of the two circular sections.
What is the work and answer of 689 divided by 23?
29.9565
What is 22422 divided by 32 with remainder?
700.6875
Why do chiller's using CFC-11 and HCFC-123 require purge units?
These refrigerants have higher boiling points than say R12 or R22. Thus when a machine using them operates the low side will run in a vacuum. So any low side leak points will suck in air rather than leak refrigerant out. A purge unit constantly samples the condenser gas and removes the air and water vapor which has been pulled in at these leaking points and periodically releases them to atmosphere while it condenses any refrigerant vapor picked up in the sample mix to a liquid and returns it to the machine.
How do you find the area for a frustum cone?
V = 1/3πh ( R12 + R22 + R1R2 )where π is 3.14159265..., and R1, R2 are the radii of the two bases.
What is the correct pressure on the high side and low side on R22 at 95 degrees?
150 high 75 low
What is the formula for the density of a truncated cone?

Can you buy r22 freon from walmart?
Wal-Mart do not have r22 freon, this is a false ad.
What is the calculation to find evaporator superheat for a system with 76 per square inch gage for R22 when the evaporator outlet temperature is 58 degrees Fahrenheit?
10
What is meant by degree of superheat?
First of all, the term "superheated" generally refers to a vapor. This explanation refers to superheated vapor only. Superheat is the difference (in degrees of temperature) between a liquid's boiling point and the superheated vapor's actual temperature. For example; at sea level, the boiling point of water is 212ºF. As long as the temperature is 212ºF, you will have both liquid and vapor present. If you continue to add heat to the liquid/vapor mix, all the liquid will eventually become vapor. Additional heat added after no liquid remains will begin to increase the temperature above 212ºF. This resulting vapor is superheated. If you measure the temperature of water vapor to be 220ºF at 1 ATM, the vapor is superheated by 8ºF. The same analysis is true for any liquid/vapor, at any pressure and for any other temperature scale. i.e. R22 refrigerant is "saturated" (meaning both liquid and vapor are present) at 32ºF and 58PSIG. If you measure the pressure of R22 at 58PSIG but measure the temperature at 45ºF, you have measured 13 degrees of superheat. I hope this answer is useful to you. Bama Cracker Degree of superheat is the difference between the superheated temperature and the saturated temperature of the steam .
Why r22 freon is not compatible with r410 freon?
Chemical composition and properties, different system pressures, different pressure/teperarature relationships in when they'll change states from liquid to vapor... you never mix refrigerants, period.
Substitute for r22?
r22a
What are the pressure on r22?
69.9
Can you mix R22 with R404A?
No
How do you calculate the volume of a flat top cone?
Take the base Radius to be R1, the top radius to be R2. Then the volume for the "cone" is V = Pi * (R12 + R1R2 + R22) * Height / 3
What should be our head pressure on a R22 unit on a 90 degree day?
265 PSI which equals 120 Degrees Fahrenheit, basically you add about 30 to 35 degrees to the outdoor ambient temperature example 90 degree day at 30 to 35degrees which equals 120 degrees on the high side
Can r22 and 22a be mixed in system?
No
