Transcribed Image Text:The diagram below illustrates the Jet-A fuel system on an aircraft. A pump pressurizes the fuel reservoir,
causing the fuel to flow through connected pipes. Points C and D are linked to the aircraft engines and
discharge fuel as free jets. Point E is connected to the Auxiliary Power Unit (APU) and discharges fuel to
atmospheric pressure. The pump reads 15 psi, and the flight altitude is 10,000 feet. For the purposes of this
analysis, we will assume there are no losses.
a) Find the atmospheric pressure at 10,000ft given ISA+5 conditions, and a mercury barometer at the
airport Mean Sea Level reads 743mmHg.
b) Draw a total head diagram of the system.
c) what would be the mass flow rate (in L/Hour) of your fuel entering both your engines and APU at
that altitude given ISA+5?
d) How long (in Hours) can this aircraft fly in the above conditions (from part b) if it is loaded with 2,500L
of fuel?
