may you answer my question in a good hand writting thank u

Question 2 (Marks 20) The volumetric flowrate, Q, through a pipe containing a slowly moving liquid is given by the equation: Q=(TRAP)/8jL where R is the pipe radius, AP is the pressure drop across the pipe, u is the viscosity, L is the length of the pipe. Check the dimensions of the left and right hand sides of the equation. Including velocity of the fluid flow (v) as one of the given variables and also given that the key variables are the pressure drop, length of the pipe and flow rate, find the number of dimensionless groups in this system and their respective formulas
