Now, this is actually less than the original quote, but still an exorbitant amount for a tablet that cost me $229. However, Iâd like to draw your attention to the above image, sent to me of my tablet by the ASUS repair center.
1 You'll feel a slack in the line. 2  At the point where you feel the slack, mark the line at the top edge of the casing (you can tie a small knot in the line, use tape or a marker). 3  Pull the line back up from the casing. 4  Measure the length of the line from the bobber to the marked line. 5  This is your static water level.
Remember that you must also take into consideration the level of the water in the suction tank. If the water level is 10 feet below the pump suction connection then the static head will be 10 + 15 = 25 feet.Therefore the total head will have to be at least 25 feet plus the friction head loss of the fluid moving through the pipes. 11.he total friction loss for piping in the system is then 9 + 3.1 = 12.1 feet. The static head as per Figure 41 is 35 feet. Therefore the total head is 35 + 12.1 = 47 feet. We can now go to the store and purchase a pump with at least 47 feet of total head at 10 gpm.
