An eight cylinder, four-stroke cycle, single acting diesel engine has a 650 mm bore and a 1400 mm stroke. What will be the developed indicated metric horsepower if the average mean effective pressure is 30 kg/cm2 at a speed of 100 RPM?

Question 1 of 27070

🔍 Key Concepts

• Indicated power formula for a reciprocating engine using mean effective pressure, stroke, bore, RPM, and number of cylinders • Difference between two-stroke and four-stroke cycles in terms of power strokes per revolution • Correct unit conversions from mm to meters and from kg/cm² to kN/m² (or N/m²)

💭 Think About

• How many power strokes does each cylinder produce per minute in a four-stroke engine running at 100 RPM? • What is the swept volume per cylinder, and how do you get the total swept volume per minute for the whole engine? • After finding indicated power in kW, which choice is closest to your result if you carefully apply the formula and all conversions?

✅ Before You Answer

• Be sure you use RPM/2 for power strokes per cylinder because it is a four-stroke engine • Convert bore and stroke from mm to meters before calculating volume • Convert mean effective pressure from kg/cm² to a consistent SI pressure unit (e.g., kN/m²) before inserting in the power formula
