Internal Combustion Engines If V₁ is the jet velocity and V₀ is the vehicle velocity, then propulsive efficiency of a turbojet engine is V₁ / (V₀ + V₁) 2V₁ / (V₀ + V₁) 2V₀ / (V₀ + V₁) V₀ / (V₀ + V₁) V₁ / (V₀ + V₁) 2V₁ / (V₀ + V₁) 2V₀ / (V₀ + V₁) V₀ / (V₀ + V₁) ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines The brake power (B.P.) of the engine is given by (where W = Brake load or dead load in newtons, l = Length of arm in meters, N = Speed of engine in r.p.m., S = Spring balance reading in newtons, D = Dia. of brake drum in meters, and d = Dia. of rope in meters) All of these P = [(W - S) π (D + d) N]/60 watts P = (Wl × 2πN)/60 watts P = [(W - S) πDN]/60 watts All of these P = [(W - S) π (D + d) N]/60 watts P = (Wl × 2πN)/60 watts P = [(W - S) πDN]/60 watts ANSWER DOWNLOAD EXAMIANS APP
