In rural areas, propane is frequently used as a fuel for home heating. A typical 500 gal propane tank, when filled, will hold 400 gal of propane at one time as a liquid (about 740 kg). One night, a farmer coming home from a community meeting accidently backs into his propane tank with his truck, knocking it over and cracking the pipe connection creating a 3 mm diameter opening at the tank. The release rate from the hole is estimated to be 0.2 kg/s, and the farmer quickly turns off his truck so the cloud is not ignited by the running truck. The LFL of propane is 2.1%, and the IDLH for flammable gases is often estimated to be 0.1*LFL. The closest ignition source is about 100 m from the leak. Could the cloud be expected to reach that ignition source and burn back to the source (LFL)? Treat the propane release as though it is an ambient temperature gas, and assume the wind speed is 1.5 m/s. State and justify all of your assumptions for full credit. (Molecular weight of propane is 44.1 g/mol).
