1. An in-line six cylinder, 6.6 liter, four-stroke cycle SI engine with multiple port fuel injection operates at 3000 RPM, with a volumetric efficiency of 89%. The intake manifold runner can be approximated as round pipes with an inside diameter of 4.0 cm. Inlet temperature to the manifold is 27°C.Calculate: a) average velocity and mass flow rate of air to each cylinder, using inlet temperature to evaluate properties.b) Reynolds number in the runner to cylinder #1, which is 40 cm long.c) Temperature of the air entering cylinder #1 if the runner wall temperature is constant @ 67C.d) wall temperature needed for the runner to cylinder #3, such that the cylinder air inlet temperature is the same as that in cylinder #1. Runner length for cylinder #3 is 15 cm.
