Buoyancy fluxes in a stratififed fluid and units
I am calculating the buoyancy flux (B) for a stratified fluid as follows:
where g = 9.81 m/s; alpha = 1.6 x10^{-5} + 9.6 x10^{-6} x (20 degC); S = 100 Wm^{-2}, p0 = 1000 kg/m3, and Cpw is the ...

What is the particle residence time for given flow rates of gas mixture components?
For two different chemical substances there are two open valves with flow rates $$Q_1=a\frac{m^3}{h}\ \text{ and }\ \ Q_2=b\frac{m^3}{h},$$ leading into seperate cables.
Next, the cables join, the ...

Why is the unit of hydraulic impedance/resistance kilogram per second and hypermeter?
I'm trying to figure out the unit of impedance in the hydraulic analogy of electronic networks. Assuming
$$Z=\frac{P}{Q},$$
with $P$ as pressure difference, $Q$ as volumetric flow rate and $Z$ as ...
