Know a good way to estimate fuel flow for a turboprop?

Hey Guys,

I need a rough estimate for how your fuel flow changes with altitude and mach number. I am trying to figure out this problem. If you are applying 1000 hp at sea level static with 100lb of fuel per hour. How much fuel (lb/h) would you need to provide to at 5000ft and a velocity of 0 ft/s. How much fuel would you need to supply at sea level going mach .3. And finally how much fuel would you need to supply at mach .3 and 5000 feet altitude.

Thanks,
