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:
Horse power = 167.84 hp
Explanation:
Horsepower is calculated using the formula;
P = T * w
See the attached file for the calculation
The program is an illustration of functions.
Functions are group of code blocks that perform as one
The ConvertToWeeksAndDays() function in python where comments are used to explain each line is as follows:
#This defines the ConvertToWeeksAndDays function
def ConvertToWeeksAndDays(totalDays):
#This calculates the number of weeks
weeks = totalDays//7
#This calculates the number of days
days = totalDays %7
#This prints the number of weeks and days
print(weeks,"weeks and",days,"days")
