It's supplied by a nearby mass of magma.
There are several information's already given in the question. Let us write them down first.
Radius of the tank = 3 feet
Height of the tank = 10 feet
Value of pi = 3.14
Then
Volume of the cylindrical tank = 3.14 * (3)^2 * 10
= 3.14 * 9 * 10
= 282.6 ft^3
Now
Heating capacity of 1 cubic foot of natural gas = 1030 BTU's
Then
Heating capacity of 282.6 cubic foot of natural gas = 1030 * 282.6
= 291078 BTU's
I hope the procedure is clear enough for you to understand.
(1/2)(5.0)(v²) = 150
v= 7.75m/s
