Solution:

Consider the following data:

P = Laser beam power = 1 kW

v = Cutting velocity = 0.01 m/s

d = Laser beam spot diameter = 0.004 m

Calculate the value of Cutting depth (in m) (Consider all other dependent parameters as constant, and equal to 0.0000001).

2.5

3.5

Solution:

The velocity of a water jet coming out of an orifice can be calculated using the following formula:

v = Ψ × √(p_w / ρ)

Where:

- Ψ is the velocity coefficient of the orifice, which is 0.97

- p_w is the pressure of the water, which is 200 bar

- ρ is the density of water, which is 1000 kg/m³

What is the velocity of the water jet coming out of the orifice?

190 m/s

194 m/s

200 m/s

None of the above
