I SPECIFICALLY need help on the BONUS question!I only included the other questions for an understanding on the scoop of the problem. - write N-S equations for incompressible flows in cartesian coordinates in long form (in x, y,z coordinates)
- also write continuity equation and N-S equations for incompressible flows in polar coordinates in long form (inr,0.2) (since one of your friends ask you can find it easily in online resources or in books)
- Write down N-S equations in x direction for Planar Couette-Pouseille flow and derive an equation for velocity variation using boundary layer conditions mentioned in the last lecture (assuming incompressible, steady and fully developed flow)
BONUS: Assume an incompressible, steady, axissymmetric, fully developed Pouseille flow in a cylindrical pipe (infinitesimally long in z direction). The flow is in z direction, and radial and tangetial velocity is zero. Derive and simplify the N-S equation in z direction to find out the velocity in z direction. (need to use the boundary conditions to solve for integration constants)

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
