Lyn 52:
ΔP<sub>EL</sub> = ρgh = ρg(h<sub>2</sub>-h<sub>1</sub>) = 958.4 × 9.81 × (0.5 - 5.5) = -47010 Pa × (1 kPa/1000Pa) = 47 kPa
: <math>\Delta P_{EL} = \rho g h = \rho g (h_2 - h_1) = 958.4 \times 9.81 \times (0.5 - 5.5) = -47010 \ Pa \times \frac{1 \ kPa}{1000 \ Pa} = -47 \ kPa</math>
Dus is:
: <math>NPSH_A = \frac{P_1 - P_{eff} - \Delta P_{EL} - \Delta P_{f}}{9.81 \ SG} = \frac{101 - 101 - (-
