A smooth pipe containing ethanol at 20°C flows at 7 m3/h through a Bernoulli obstruction, as in Fig. P6.148. Three piezometer tubes are installed, as shown. If the obstruction is a thin-plate orifice, estimate the piezometer levels (a) h2 and (b) h?. h3 d=3cm D=5cm Fig. P6.148

how to calculate the total head loss of this system? Do you just add all the head losses of the all the pipes?

when you calculate the bernoulli between pipe 1 and 2 you wrtie P1 is 79, 7 x 10^3 so why ?
