solve 20-30 mins i'll give you multiple upvote( handwritten asap)How can I solve the problem below in viscous fluid flow?
Please don't use Artificial intelligence tools. Only Handwritten solution
I need solve this in quickly time please please
liquid (density 800kg/m3, viscosity 10−3 kg/ms) has to be supplied at a mean speed of 2m/s through a pipe of diameter 12.5mm with a surface roughness equivalent to that for structural steel. What is the magnitude of the pressure gradient necessary to achieve this flow? Your answer should have a positive sign and be to the nearest 10 Pa/m. You may wish to use the Moody diagram.

Consider a steady, incompressible, y=+h ↑y hydrodynamically fully-developed flow between two infinite flat plates as shown. The flow can be described by the following equation: y=-h 2U K -y² +C¸y+C, 2µ where u is the dynamic viscosity, u is the axial velocity (i.e., the velocity in x-direction), and K, Cı, and C2 are constants. (a) Obtain the velocity profile u(y) in terms of h, U, K, µ̟ and y. (b) For what value of K is the shear stress zero at y=h/2. Consider h=0.01 mm, U=0.1 mm/s, and u=0.001 Pa.s
