You are asked to design a four cylinder four-stroke spark ignition engine for a passenger car, which is required to provide a maximum brake torque of (2.60x10^2) Nm at the rated speed of (7.000x10^3) rpm. To simply the design, the bore (B)/stroke (L) ratio is assumed to be unit, i.e. B=L. Given that the bmep of the engine is assumed to be (7.000x10^2) KPa, find its mean piston speed. The answer should be in the unit of m/s with 3 significant figures.
