Answer:
The efficiency of the engine is 22.5%.
Explanation:
Efficiency = power output ÷ power input
power output = 55 kW
power input = specific energy×volumetric flow rate×density
specific energy = 44,000 kJ/kg
volumetric flow rate = 27.4 L/h = 27.4 L/h × 1000 cm^3/1 L × 1 h/3600 s = 7.61 cm^3/s
density = 0.73 g/cm^3 = 0.73 g/cm^3 × 1 kg/1000g = 7.3×10^-4 kg/cm^3
power input = 44,000 kJ/kg × 7.61 cm^3/s × 7.3×10^-4 kg/cm^3 = 244.4332 kJ/s = 244.4332 kW
Efficiency = 55 ÷ 244.4332 = 0.225 × 100 = 22.5%

Answer:
Option D
Material has uniform properties throughout.
Explanation:
A homogeneous material is a material that exhibits uniform properties throughout and these properties cannot be separated. These materials can be metals, ceramics or alloys that exhibit similar properties throughout. The similar properties may include evaporation point, density and other properties.
