Show Attempt History Current Attempt in Progress A certain gasoline engine has an efficiency of 34.0%; that is, it converts into useful work 34.0% of the heat generated by burning a fuel. + Problem Set 2 1 of 3 0.5/1 * This is a scaling/unit conversion problem; be careful with units. Suppose the fuel is changed to include 85.0% ethanol by volume. The heating value of ethanol is approximately 2.34 x 104 kJ/L and volumes of gasoline and ethanol are assumed to be additive. At what rate (L/h) does the fuel mixture have to be consumed to produce the same power as gasoline (consumed at 1.80 L/h)? i 1.70 L/h Hint Save for Later
