Theory of Machine The advantage of the piston valve over the slide valve is that in the former case Wear is less Both wear and power absorbed are low Power absorbed is less The pressure developed being high provides tight sealing Wear is less Both wear and power absorbed are low Power absorbed is less The pressure developed being high provides tight sealing ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The velocity of piston in a reciprocating steam engine is given by (where ω = Angular velocity of crank, r = Radius of crank pin circle, θ = Angle turned by crank from inner dead center, and n = Ratio of length of connecting rod to the radius of crank) ωr [sin θ + (sin 2θ/n)] ω²r [cos θ + (cos 2θ/n)] ωr [cos θ + (cos 2θ/n)] ω²r [sin θ + (sin 2θ/n)] ωr [sin θ + (sin 2θ/n)] ω²r [cos θ + (cos 2θ/n)] ωr [cos θ + (cos 2θ/n)] ω²r [sin θ + (sin 2θ/n)] ANSWER DOWNLOAD EXAMIANS APP
