<span>P1V1/T1=P2V2/T2
isolate V2 and calculate
remember the temperature has to be in Kelvin
K=C+273
the pressure in this case is not necessary to convert to atm you can use the mmHg you will get the same answer</span>
Answer: 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.
Answer:
n = 1.523
Explanation:
Snell's law
1.273sin32.89 = nsin26.99
Answer:
About 6.26m/s
Explanation:
Divide both sides by mass:
Since the point of equality of kinetic and potential energy will be halfway down the cliff, height will be 4/2=2 meters.
Hope this helps!
