The Hand Pump Volume calculator computes the number of pumps or cranks (depending on the pump type) to pump the desired volume (V) based on the known cranks or pumps (c) per specified volume (VPC)

INSTRUCTIONS: Choose units and enter the following:

• (c) - This is the specified number of cranks or pumps on the hand pump to produce the VPC.
• (VPC) - This is the specified volume pumped with the specified number of cranks or pumps  (c) on the hand pump
•  (V) - This is the desired volume of liquid you wish to have pumped.

CRANKS: The calculator returns the number of cranks or pumps needed to pump the specified volume.

I don't know my VPC:  If your pump has documentation, it may tell you the volume per pump.  In some cases it says things like 10 gallons in 100 pump (cranks).  In this case you would enter 100 for c and 10 for VPC.  If this isn't in your documentation, it's easy to derive.  Take a container of known volume.  I suggest a 5 gallon bucket, and count how many pumps it takes to fill the bucket.  Note: do not count the priming pumps before the flow begins.  In this example, the VPC would be 5 gallons and number of pumps (c) would be the number of pumps it took to fill the bucket.

(d) of the liquid content of the AST.                     Above ground Storage Tank with diesel fuel

These pictures show an above ground storage tank with diesel fuel with a hand crank that pumps 10 gallons for every 100 turns of the pump crank.  During cold periods, the fuel supplier will treat the diesel with an anti-freeze mixture, but this is only a concern if the temp is well below zero degrees F (e.g.-5 F or colder).
