if the evaporator oulet temperature on an r-410A system is 50f and the evaporator superheat is 10f, what is the evaporating pressure of the refrigerant in the system

143 psig

Explanation:

Given data:

System heat = 50f

Evaporator superheat = 10f

System = r410a.

Solution:

Evaporating pressure of the refrigerant in the system

= system heat - evaporator superheat.

= 50f - 10f

= 40f.

Using the r-410a temperature chart

40f = 143 psig.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
