Practical Problem Solving Flashcards
1
Q
What are the common assumptions for ideal gases in thermodynamic problems?
A
- No intermolecular forces
- Volume of molecules is negligible
- Follows PV = nRT
2
Q
How is mass flow rate (m.) calculated for steady flow systems?
A
m. = ρVA / t
Where
ρ: Density
V: Velocity
A: Area
t: Time
3
Q
What is a heat exchanger?
A
A device that transfers heat between two fluids without mixing them.
4
Q
What us the steady flow energy equation (SFEE)?
A
Q - W = m. (h_2 - h_1)
Where
m. : Mass flow rate
h_1 : Inlet enthalpy
h_2 : Outlet enthalpy
