simple btu conversion problem 4

[strongone]

I would like to know the conversion of: $/litre to $/million Btu for diesel

First get the data for the grade of fuel you want to check.

1. Density
2. Calorific Value (net)

Now the calculation is simple.

Mass of fuel in kg = volume in liters x density in kg/lit
Now, multiply calorific value (in btu/kg) with cost $/Kg to get $/Btu.

For example, one grade of diesel we use has a density of 0.87 kg/liter and the calorific value is 10000 kCal/Kg. The cost of fuel is 18 Rs/Kg

So one liter of fuel mass is 0.87 kg. Total calorific value is 0.87 x 10000 = 8700 kCal. so unit rate is 18/8700 = 0.002 Rs/kCal.

You can download a very good unit conversion software program from the link below.

Just thank the owner of this program Katmar who is also one of the great members of this website.

Following quark's advice, assume 0.870 kg/L for density, and 41,000 Btu/kg as gross calorific value, and obtain 41,000(0.87)~35,700 Btu/L.

So, the price X$/L=X$/35,700 Btu

==>(X)1,000,000/35,700 $/million Btu ~28(X) $/million Btu.​

huh...now I got it. The stars are for the link I
providedB-( How about passing them to Katmar instead, unless you guys want to embarass me for a whole lifetime.

Hey quark, now you are embarassing me!

You deserve the stars for all the helpful hints you give here, over such a wide range of subjects.
