Sagot :
The velocity of propagation is v = 3.836 m/s ± 5%
Data;
- diameter of tank = d = 300 ± 10 % mm
- initial height of tank H = 1m
- Exit tank diameter (Orifice) = d = 2 ± 10%
Velocity of Flow of Orifice
The velocity of the flow is calculated as
[tex]v_h = \sqrt{2gh}[/tex]
h = height of the fluid from the orifice
h = 0.75 ± 10%m
[tex]v = \sqrt{2*9.81*0.75}\\g = 9.81 m/s^2\\v = 3.836 m/s[/tex]
The uncertainty or error in calculating velocity
[tex]v = \sqrt{2gh}[/tex]
The uncertainty = 1/2 * error in 'h'
[tex]\frac{1}{2} * 10 \% = +5 \%[/tex]
The uncertainty = ± 5%
The velocity of propagation is v = 3.836 m/s ± 5%
