Answer 1

A fluid of density 2 into 10 raise to power cube kg/m cube is flowing in horizontal pipe. the speed of water at point A is 4cm/s, what is its speed at point B (Height=2.5mm)

Bernoulli's principle can be expressed as a mathematical equation:

$$\frac {v ^ {2}}{2} + g h + \frac {p}{\rho} = c o n s t$$

where $v$ is the fluid flow speed, $g$ is the acceleration due to gravity, $h$ is the height, $p$ is the pressure, and $\rho$ is the density of the fluid.

In our case:

$$\frac {v _ {A} ^ {2}}{2} + g h = \frac {v _ {B} ^ {2}}{2} + 0$$ $$v _ {B} = \sqrt {v _ {A} ^ {2} + g h} = 22.5 \frac {c m}{s}$$

Answer: 22.5 $\frac{cm}{s}$
