## pressure and velocity

Can you guys help me how to solve the Flow rate if i have 1 inch pipe with a 30 psi pressure,... actually my problem is how to get the velocity... i have some reference but its a simulation factor.. if i will use the given formula Q=Velocity x Area where velocity is equal to Square root of 2 x gravity x Height the result is too big

example 2inch pipe has a 20 m/sec velocity resulting on 600 GPM based on the formula but on the actual 2" can only have maximum of 250 - 300 gpm @ 30 to 40 PSI.. i hope some one could help me correct the formula im using thanks !!
