For a Newtonian fluid flowing in turbulent flow conditions, show the effect of increasing the flow rate by 2 times on the pressure difference and the effect of increasing the pipe diameter by 25% on the pressure difference mathematically (without using numerical values). On the condition that everything else remains constant, show the effect of increasing the pipe diameter on the flow, the effect of increasing the pipe length on the pressure difference and the effect of increasing the pipe length on the flow mathematically (without using numerical values).Show mathematically (without using numerical values) how the pressure difference will be affected if you use two parallel pipelines with a length equal to half the length of the first pipe and equal diameter to the first pipe instead of one long pipeline.
* Your answer is incorrect. In the equation ly = ky²A, ky is the: Radius of gyration - the measure of the distribution of the area from the y-axis. Perpendicular distance from the y-axis to the centroid of the area. Diameter of gyration - the measure of the distribution of the area from the y-axis. Perpendicular distance from the z-axis to the centroid of the area.

Q.37 Water is moving through a pipe. The velocity profile at a particular section is given mathematically as V = v- (1) (²²-2²) 4μ 4 where v = velocity of water at any position r B: = constant μ = viscosity of water d = pipe diameter r = radial distance from centreline of pipe (i) What is the shear stress at the wall of the pipe due to the water? (ii) What is the shear stress at a position r= d/4? (iii) If the given profile persists a distance L along the pipe, what drag is induced on the pipe by the water in the direction of flow over this distance?
An open horizontal tank 2 m high, 2 m wide and 4 m long is full of water. Determine the amount of water spilled out when the tank is accelerated horizontally at 2.45 m/s2 in a direction parallel with its longest side in m3. Find the force acting on the side with the greatest depth in kN. note: Please write the final answer in two decimal places. Please write the correct unit Please write legibly It would be better if the solution could be typewritten Thank you
Fluid often passes through pores in cell membranes or cell layers. The dimensions are small and the velocities low, so viscous forces dominate (low Reynolds number). Use dimensional analysis, or an approximate method of analysis based on the viscous flow equations, to determine the scaling law that expresses the dependence of the pressure drop across a pore (ΔP) on the flow rate through it (Q). The other parameters that are given include the pore radius, R, and the viscosity of the fluid, μ. The membrane itself should be considered infinitesimally thin so that its thickness does not influence the pressure drop.

Sketch the Maxwell model and label all the components. Also, draw a graph of displacement versus time when the model is subjected to a constant force for a time period and then released. Why does the model responds this way.
d) The viscosity of a fluid is to be measured using a viscometer constructed of two 750 mm long concentric cylinders. The outer diameter of the inner cylinder is 150 mm and the gap between the two cylinders is 1.2 mm. The inner cylinder is rotated at 200 rpm and the torque is measured to be 10 Nm. a) Derive a generals expression for the viscosity of a fluid using this type of viscometer, and; b) Determine the viscosity of the fluid for the experiment above.
