                More conversions. You will get the following information:



                 Gasoline consumption in gallons per hour           Density, 1 liter weighs 0.72 kg

                 Fuel Flow 6.8 US. Gall./hour                       Gravity 0.72






                Fill in the form below:


                             Distance        GS         Time       US. Gall.  Liter           Kg.


                               56            68




                First, we calculate the flight time. We know that we use 6.8 US. Gall. per hour.

                We therefore place the hour mark below 68.




                The distance is 56. Therefore, the arm is placed so

                that the red line is above 56 on the distance scale.


                On the minute scale (i.e. just below 56) we read

                49.4.

                The 49.4 is converted to minutes and seconds:


                    49 min. and 4٠6 sec. = 49 min 24 sec (which is entered in the table under Time)




                The next value we need to find is the US.Gall. for 49.4 min.


                Since the consumption is 6.8 US.Gall/hour, we place the hour mark below 68 on

                the distance scale.

                The arm is turned so that the red

                line is above 49.4 (the time we

                are flying) on the minute scale.


                On the distance scale (above the minute scale) the number of US. Gall is read:

                5.6 US.Gall.
