Question

SORU 26 The pump shown in Fig. 4 adds a 15-ft head to the water ($\rho$ = 1.94 slugs/ft$^3$, $\mu$ = 2.34 × 10$^{-5}$ lbf-s/ft$^2$ and $\gamma$= 62.4 lbf/ft$^3$) being pumped from the upper tank to the lower tank. If the pipe has a roughness $\epsilon$ = 0.003 ft, determine the flow rate Q. Use $f$ = 0.03 as the initial guess then the following equation for the remaining iterations until $f$ converges to the thousandth decimal place. (Note: 1 psi = 144 lbf/ft$^2$ and g = 32.2 ft/s$^2$) $\frac{1}{\sqrt{f}}$ = -1.8 log$\left[\frac{\epsilon/(D)}{3.7} + \frac{6.9}{Re}\right]$

The pump shown in Fig. 4 adds a 15-ft head to the water (ρ = 1.94 slugs/ft^3, μ = 2.34 × 10^-5 lbf-s/ft^2 and γ= 62.4 lbf/ft^3) being pumped from the upper tank to the lower tank. If the pipe has a roughness ϵ = 0.003 ft, determine the flow rate Q. Use f = 0.03 as the initial guess then the following equation for the remaining iterations until f converges to the thousandth decimal place. (Note: 1 psi = 144 lbf/ft^2 and g = 32.2 ft/s^2)
(1)/(√(f)) = -1.8 log[(ϵ/(D))/(3.7) + (6.9)/(Re)]
