Supporting Information

Bend meter

(Cd ~ 0.60 for comparison with experimental value)

Nominal pipe diameter = 80 mm

Q = Cd x a x √(2g) x h0.5

 

Venturi meter

(Cd ~ 0.97 for comparison with experimental value)

Approach pipe diameter = 80 mm and throat diameter = 38 mm

Q = Cd x a1 x √(2g/(k2 – 1)) x h0.5

Where k = a1/a2 (a1 and a2 is the upstream pipe and throat diameter, respectively)

 

Pitot tube meter

(Cd ~ 0.99 for comparison with experimental value)

Nominal pipe diameter = 80 mm

Q = Cd x a x √(2g) x h0.5

 

Orifice meter

(Cd ~ 0.66 for comparison with experimental value)

Approach pipe diameter = 80 mm and throat diameter = 26 mm

(Discharge equation identical to Venturi)
