Pounds per square inch (PSI) x 2.31 = Feet head (of water)

30 psi = 69.3 feet ~ 69' 3"
40 psi = 92.4 feet ~ 92' 5"

You will need to add this much height to overcome the pressure loss in 60
feet of pvc pipe :
SCH 40 PVC: 12.8 feet
SCH 80 PVC: 14.7 feet

Add 2' of height per gal/min of flow rate for Head Loss:

Note:
9 gal/min = Max flow rate for SCH 80 pipe
11 gal/min = Max flow rate for SCH 40 pipe

Plus add 1' of height per coupler, 2' per 'ell', and 5' per 'tee'

Finally, you'll need to add additional height to give you the additional
water pressure you'll need based on the equation at the beginning of this
reply.

If you intend to use a different type of pipe, please let me know and I'll
be happy to post the results for that type.
