An experimental setup is being built to study the flow in a large water main (i.e., a large pipe). The water main is
expected to convey a discharge (Qp). The experimental tube will be built at a length scale of 1/20 of the actual
water main. After building the experimental setup, the pressure drop per unit length in the model tube (APm/Lm)
is measured.
Problem (19): Given the value of Qp [m³/s], and assuming Reynolds number similitude between the water main
and experimental tube, calculate the flow rate in the model tube (Qm) in [lit/s].
= 30.015 m^3/s
