HEAT TRANSFER (Internal Combustion Engine Question)

A 3.0 liter,5-cylinder, 4 -stroke cycle SI engine, with a volumetric efficiency of $82 \%$, operates at 3000 RPM using gasoline with a lambda value of 0.91. Bore and stroke are related as $S=1.08$ B. At a certain point in the engine cycle, the gas temperature in the combustion chamber is $T_{g}=2100^{\circ} \mathrm{C}$ while the cylinder wall temperature is $T_{w}=190^{\circ} \mathrm{C}$. Calculate the approximate convection heat transfer rate to the cylinder wall at this instant.
