engineering recuitment UPPSC AE Mock Test 2024 Internal Combustion Engine Engine Performance Parameter Power and Efficiency
What will be the brake power (BP) of the engine if it is tested with a rope brake dynamometer?
Given, W = Dead load (in Newtons), S = Spring balance reading (in Newtons), D = Diameter of the wheel (in metres), d = Diameter of the rope (in metres) and N = Speed of the engine shaft (in RPM)
1
BP = \(\frac{(W-S) \pi(D-d) N}{60}\) Watts
2
BP = \(\frac{(W+S) \pi(D+d) N}{60}\) Watts
3
BP = \(\frac{(W-S) \pi(D+d) N}{60}\)Watts
4
BP = \(\frac{(W+S) \pi(D-d) N}{60}\)Watts
