SUMMARY

The discussion focuses on determining the pressure of Refrigerant 134a at a temperature of 60°C and a specific volume of 0.072 m³/kg, which falls within the superheated region. The required pressure is calculated to be 3.63 kPa using double interpolation techniques. A reference link to a detailed explanation of the interpolation method is provided, which can assist in understanding the calculation process.

For Refrigerant 134a at T = 60C and v = 0.072 m3/kg,
determine pressure in kPa.

the v is in superheated region so I have a mini table look like in the picture I've added
there I need to do a double interpolation but don't know how. the anser for p is: 3.63Kpa.
Thanks

Thread 'Truss analysis problem'

TL;DR: determine the internal force of member OA Hi I'm struggling with this problem. I have calculated the angle to be 45 degrees with tan(theta) = a/a. A is a roller which only has Ay and O has Ox & Oy as a fixed pin. (see fbd.png) is my FBD correct?
