INTRODUCTION TO MOMENTUM TRANSPORT
Learning outcome:
Momentum flux
# Momentum = mass(kg) x velocity (m/s)
# Momentum flux = rate of transfer of momentum / area
# Unit for momentum flux = Pa
Momentum Transfer Equation - Newton's Law of Viscosity
Total Molecular Transport
Molecular stresses = Pressure stress + Viscous stress
Learning outcome:
- Explain the relationship of momentum flux, stress and viscosity
- Estimate the viscosity of fluids
- Derive the equations of convective transport
