8.24. A small blower is required to supply 250 cfm with a static pres- sure rise of 8 in. wg and an air weight density of pg = 0.053 lbf /ft°. Develop a centrifugal flow path for an SWSI configuration. Use the optimal d/D ratio for minimum W1, estimate the slip using the Stodola formula (µE ~ 0.9), assume polytropic density change across the blade row (using Cordier efficiency), and size the impeller outlet width by constraining 25° < B* < 35°.

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.
