- Homework Statement
- Water flows between Horizontal plates 1.5 cm apart and 50 cm wide with a Reynolds number of 1500. Calculate: (a) the flow rate

- Relevant Equations
- ##Q=-\frac {2Wh^3} {3\mu} (\frac {dp} {dx})##

##Re=\frac {\rho u L}{\mu}=\frac {uL}{\nu}##

I know how to derive the formula, but I have no idea how to actually use this. Where it says ##50~cm## wide, I'm not sure if that's in the x-direction or the z-direction. ##W##, the width in the equation, is in the z-direction. ##\mu## can be calculated, but I'm not sure what the pressure gradient is.
