Viscous flow through Two Parallel Plates

Q. The velocity distribution for flow between two fixed parallel plates

1. is constant over the cross-section
2. is zero at the plates and increases linearly to the mid-plane
3. varies parabolically across the section
4. is zero in middle and increases linearly towards the plates

Q. In a laminar flow between two static parallel plates, the velocity at mid-point is found to be 2.0 m/s. If the space between the plates is 10 cm, then the discharge per unit width $\left({inm}^3\text{/}s/m\right)$ will be

1. 0.01
2. 0.02
3. 0.10
4. 0.20

Q. For laminar flow between parallel plates separated by a distance 2h, head loss varies

1. $Directlyash$
2. $Inverselyash$
3. $\text{Inversely as}{h}^2$
4. $\text{Inversely as}{h}^3$

Q. In a laminar flow between two fixed plates held parallel to each other at a distance d, the shear stress is:

1. Maximum at plane $\frac{d}{2}$ away from each plate and zero at the plate boundaries.

2. Zero throughout the passage.

3. Maximum at the plate boundaries and zero at a plane $\frac{d}{2}$ away from each plate.
