Can i find the flow inside the pipe from the pressure at the point, diameter of pipe and the properties of service inside the pipe?

Hi ,
If you know the head loss between 2 points (straight pipe ) equipped with pressure Gauges calibrated , the length of the pipe ,the ID, rugosity of the pipe , the properties of the fluid , you can calculate the flow rate or velocity .
You will get a good estimate .
Check for Darcy-Weisbach equation.
Good luck

Is there anyway of doing estimation of flow rate or velocity of fluid without that?

Not really, at least not with just the data you mentioned (pressure, diameter, fluid properties). There are design criteria that can be used for preliminary line sizing during the design phase of the line (i.e. before the the line was actually built), you might use these to get the order of magnitude, but nothing more. Also, the line might not be operated like it was designed to.
I would suggest you have a measurement taken with a clamp-on flow meter.

you will find some suitable excel sheets in the next post Include

Pipe capacity - contradiction - and flow velocity for both oil and gas flow
