Water at 10°C has a kinematic viscosity of 1.30 X 10-6 m2/s flows at the rate of 896.61 L/min from the reservoir and through the pipe shown in the Fig. below. Compute the pressure at point B, considering the energy loss due to friction, but neglecting other losses. Also, use pipe roughness of 1.50 X 10-6 m. Hint: Use the appropriate formula to determine the friction factor, f to 4 decimal places (flow type dependant); g = 9.81 and round off to 3 decimal places for all other step calculations leading to the final answer including the final answer.
