Add 30° to the outside ambient air temperature (70° is the outside air temp. add 30° that gives you 100°).
Take your P/T chart and see what the head pressure (high pressure line) crosses up to at 100°.

What is the condensing temp for a head psi of 296 psig for an r22 system?
The condensing temperature for an R22 system with a head pressure of 296 psig would typically be around 120-130°F. This is based on the saturation temperature corresponding to a pressure of 296 psig on the R22 pressure-temperature chart.

What is the ac pressure supposed to be on a 88 cadillack deville?
have to get a chart. It all depends on ambient temperature. High pressures can range from 150 psi to 300 psi depending on ambient
What are the pressure on r22?
The pressure for R22 refrigerant varies depending on the temperature and phase of the refrigerant. For example, at 40°F, the pressure can be around 60 psi on the low side and 185 psi on the high side. It's important to consult a pressure-temperature chart for specific values.
What is pressure temperature chart?
Used to Charge air conditioner - as ambient temperature increases gas pressure also increases. So when charging a/c systems, chart is referenced to make sure that proper amount of refrigerant is used
How do you calculate the ambient temperature?
To calculate the ambient temperature, you can use a thermometer to measure the temperature of the surrounding air. This measurement will give you the ambient temperature, which is the temperature of the environment around you.
What information can be found on a wire derating chart?
A wire derating chart provides information on how much current a wire can safely carry based on factors such as wire size, insulation type, and ambient temperature.
