Andy: Yes!! and by your question you indicate that you do not have much experience in Hydro work
There are, as well, software that can be used to calculate the volume and the friction losses at defined carrying water volumes. What do you want to do ?. There are many in this group that can calculate or estimate the power available in each site. 70 feet = 21.3 meters 900 feet = 214 meters 18 feet = 5.48 meters 32 " = 812 mm =0.812 meter Assuming 1.5 meter/sec water velocity in the pipe. Volume = PI * (0.812/2)* 1.5 = 0.518 M^3/sec. Power= Head * volume * gravity* efficiency gravity* efficiency === 0.6 assumed. 5.48 * 0.518 * 6 = 17 KW ========== Of course this is a crude calculation since I have not calculated the friction losses and the water velocity is minimized for low friction losses.
