It runs for 3.5 hours on 1.05 gallons of gas, so it will burn about 0.3 gallons per hour at half load. A full 24 hours operating at 50% capacity will go through 7.2 gallons of gas (0.3 gal/hour x 24 hr = 7.2 gals).
WebOct 9, 2024 · According to mass conservation, the natural gas pipeline flow rate before the leak point can be obtained by Q−’ = K + Q+’, and Q−’ is inserted into step 1 to calculate the new K’ and ’. This process is iterated until the calculation results of the natural gas leakage rate tend to be stable. WebFor many gases, k ranges from about 1.09 to about 1.41, and thus. [ ( k + 1 ) / 2 ] k / ( k - 1 ) ranges from 1.7 to about 1.9. which means that choked velocity usually occurs when the …
