Friction loss is the amount of water pressure lost due to friction caused by the pipe. It is affected by:
Water flow rate
Diameter of pipe
Material the pipe is made from
Length of the pipe
This calculator can help you estimate the amount of pressure your pump must create to deliver the required amount at the destination. Also realize that various types of pipe have maximum pressure levels they can handle without rupturing.
It computes the total resistance for a system with up to two types of pipe.
Voltage Loss Calculator
Voltage loss is the amount of voltage lost due to inefficiencies in transmission over electrical wires. It is affected by:
Gauge of wire
Length of wire
After you know the type of pump (or other device) you will be powering and the length of wire between your solar panels and the device, you can use this calculator to determine the correct gauge of wire and the power your panels must be able to supply.
Tank Volume Calculator
This calculator computes the capacity of round tanks of various sizes and fill levels.
Use it to determine the proper tank size, based on your water storage and usage requirements.
Note that you can also see the weight of the water; this will be important for constructing a stable tank foundation.
Pipe Volume Calculator
This calculator computes the volume and weight of water inside a pipe. It's important information for properly constructing a pipe system.
