Data Sheet
Area of measuring tank A = 0.12 m2
Acceleration due to gravity (g) = 9.81 m/sec2
Diameter of nozzle, d=0.01 m
Density of water (ρ) = 1000 kg/m3
Weight of aluminum disc with rod, WD+R=0.195 kg
Weight of flat vane, WF=0.024 kg
Weight of hemispherical vane, WH=0.040 kg
Weight applied on the disc= WA
Formulae:
Discharge Q=(A*R)/t m3/sec
V=Q/A
Fx=ρaV2 (for flate plate vane)
Fx=2ρaV2 (for hemispherical vane)
W=WD+R+ WF+WA (for flat plate vane)
W=WD+R+ WH+WA (for hemispherical vane)
Fth=Wg
Error=(Fx-Fth)*100/Fx%
For flat plate/hemispherical vane:
| SNo. | WAKg | R1(cm) | R2(cm) | R(cm) | t(sec) | Fx (for flat plane vane) |
Fx (for hemispherical vane) |
Fth g | Error% |
