Find the brake power of a four-stroke 4 cylinder engine having brake mean effective pressure 9 Kg/cm2, piston displacement 1178.09 cm3 and the crankshaft of the engine rotates at 2000 rpm.

Find the brake power of a four-stroke 4 cylinder engine having brake mean effective pressure 9 Kg/cm2, piston displacement 1178.09 cm3 and the crankshaft of the engine rotates at 2000 rpm. Correct Answer 94 Hp

Brake power = Pmb*(L*A)*k*n/60 = (9 Kg/cm2*1178.09 cm3*4*(2000/2))/60 = 706854 kg-cm/s = 7068.54 kg-m/s = 94.24 hp Where Pmb = Brake mean effective pressure

Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?
