# A single plate dry clutch transmits $15 \mathrm{~kW}$ power at $1200 \mathrm{rpm}$. The clutch sustains a maximum axial load of $2.65 \mathrm{kN}$. The ratio of outer to inner diameter of the frictional surface is 1.25: 1 . Considering uniform wear with a coefficient of friction of 0.3 on both the frictional surfaces, the outer diameter of the clutch plate is__________mm

Next Question :

A precision seed planter can plant 10 seeds per revolution of the metering plate with a row to row distance of $450 \mathrm{~mm}$ at a speed of $6 \mathrm{~km} \mathrm{~h}^{-1}$. A plant population of 36 plants per square meter is desired for the crop. The germination percentage of the seed is $90 \% .$ If the planter ground wheel has a rolling radius of $350 \mathrm{~mm}$, the speed ratio of metering plate to the ground wheel required to obtain the desired plant population is_______________
