A spherical seed of 1 cm diameter is buried at a depth of 1 cm inside soil (thermal conductivity of 1 Wm-1K-1) in a sufficiently
large planter. There is a 1 cm thick layer of mulch (thermal conductivity of 2 Wm-1K-1) on top of the soil. The planter has top surface dimensions of 10 cm by 10 cm and is exposed to 200 Wm-2 of heat. You find the top surface temperature of the mulch (Ts,1) to be uniform at 50˚C. What is the surface temperature of the seed (Ts,2) in ˚C

Explanation:
Given
Diametrical Pitch
where T= no of teeths
D=diameter
module(m) of gears must be same
Let be the gears on two gears
Therefore Center distance is given by
thus
and Velocity ratio is given by
From 1 & 2 we get
