Pipeline flow velocity calculation

Question: Formula for calculating flow velocity in a short pipe (Problem description: Given a pressure difference of 0.4 MP at the pipe ends, pipe length L=1.8 m, and pipe diameter D=0.15 m, determine the flow velocity of the water inside the pipe). A specific formula is needed, along with the names and units of each parameter.
A pressure drop of 0.4 MPa over such a short distance? The flow velocity inside the pipe is related to whether the pipe is filled with liquid.
The flow rate is related to the flow volume and pipe diameter, but not to anything else.
It’s just a randomly given pressure difference between the inlet and outlet; what’s important is that everyone can provide the calculation formula. . . I saw Baidu state that H = (v^2*L)/(C^2*R) (free flow from a long pipe). . . And what is the standard for the so-called length-to-diameter ratio of short and long tubes?
I don’t quite understand; you can refer to the suggestions from above – what they said is all very good
I need to find those fluid calculation formulas; the choice of Reynolds number may also be relevant.
The formula is easy to find; it’s just that I’m not entirely sure about the scope of its application, and I’m not clear on the meaning of some of the parameters
Friends who are interested in this issue can take a look; my problem was completely resolved using this website. http://wenku.baidu.com/link?url=p9I2lUfIJ-lcBZ0N2fY0i7C1tYsBqvbzX-H_78-bCIta5nVnSS41KXjoNwcVzJlNR7rQ_fmHhNmf_fFsSKxObesRCTW1RbRLalmbKFUroj7
So this question essentially boils down to how to calculate traffic
