Calculate heating/cooling time and visualize temperature profile
The overall heat transfer coefficient (U) is calculated as:
1/U = 1/hvessel + 1/hjacket + Rwall
Where hvessel and hjacket are convective coefficients, and Rwall is the wall resistance (neglected in this calculator).
Agitator performance is characterized by:
Re = ρNDa²/μ
Nu = hD/k
Pr = Cpμ/k
Where ρ is density, N is rotational speed, Da is agitator diameter, μ is viscosity, Cp is specific heat, k is thermal conductivity.
