For the centrifugal water pump of Prob. 1428, plot the pumps performance data: H (m), bhp (W), and hpump (percent) as functions of V . (Lpm), using symbols only (no lines). Perform linear least-squares polynomial curve fits for all three parameters, and plot the fitted curves as lines (no symbols) on the same plot. For consistency, use a first-order curve fit for H as a function of V . 2 , use a second-order curve fit for bhp as a function of both V . and V . 2 , and use a third-order curve fit for hpump as a function of V . , V . 2 , and V . 3 . List all curve-fitted equations and coefficients (with units) for full credit. Calculate the BEP of the pump based on the curve-fitted expressions.
