A turlough is a unique type of seasonal lake found in Irish karst areas which are formed through the annual welling-up of water from the underground water system. Water supplies from wells in karst topography may be unsafe, as the water may have run unimpeded from a sinkhole in a cattle pasture, through a cave and to the well, bypassing the normal filtering that occurs in a porous aquifer.
A battery rated at 180 amp-hours over 6 hours might be rated at 220 AH at the 20-hour rate, and 260 AH at the 48-hour rate. Much of this loss of efficiency is due to higher internal resistance at higher amperage rates-internal resistance is not a constant-kind of like the more you push, the more it pushes back.
Watt hours to amp hours calc. Used to convert the measured watt hours over the time as measured on a meter to the equivalent daily watt hours, of the device measured. Watt Time in days = Watt Time in hours / 24 hours in a day. Watt Hours per day = Watt Hours / Watt Time in days. Watt hours per day is then converted to the equivelent battery amp hours at the systems voltage. Average Amp per Hour = Watt Hours / Watt Time in hours / Battery voltage. Total Amp hour per day = Watt Hours per day / Battery voltage. Enter the values then press Calculate.
