Can someone please tell me what the volume of water is, in gallons, of a 50
metre length of garden hose.

Thinking of making a heat exchanger to heat up the water in a big box with
50 metres of garden hose snaked out and under a Perspex cover

There has to be a calculation somewhere bit I don't know.

Thank you.

Mike

If it has an internal diameter of 13mm, it has a cross section of
0.000133 m^2, so the volume of the pipe is 6.65 litres (I think that's
about a gallon and a half).

If a hose has an internal diameter of 13mm, then

13mm*13mm*PI *50m

= 1.3cm * 1.3cm * 3.1415 * 5000cm

= 26546 cubic cm

= 26.5 litres

= 5.8 gallons

If the interior diameter of said hose is .5 inch, that would be 1.37
gallons (?)

13 mm diameter = 6.5 mm radius.

The diameter is probably about 2 cm.
The cross sectional area is then 3.142 square cm
The volume will be 15710 cc, or 15.7 litres
At approximately 4.5 litres per gallon, this comes to about 3.5
gallons.

That's a really big hose! I just had to stretch mine like mad to get it
over a bit of 15mm copper pipe.

Oops, well spotted. In which case, it's a quarter of what I said

= about 1.5 gallons

13mm*13mm*PI *50m

Divide by 4

I probably overestimated the diameter. Unless I am wrong, most
household hoses will have an internal diameter of 1/2", or 1.25 cm.
If that is a better estimate for the diameter, the volume in gallons
comes down to 1.37 gallons.

Yes. I think I did overestimate the diameter of a "retail" hose. I
figured on a 3/4" diameter, but 1/2" is probably more nearly right.
In that case the volume comes down to 1.37 gallons.

I would have thought you would have used a header tank and a circulating
pump, in which case the volume is not important.
Have you thought of using black alkathene pipe, whilst it is a bit more
expensive you can get a better range of sizes and being black it will
absorbed more heat.
You say under a Perspex cover, if you can insulate under the pipe and then
have a reflective surface on top of the insulation then for the top use
something like Correx (Double skin sheet ) you will get more heat in the
unit.
