Undisturbed soil sample is collected from a field when the soil moisture is at field capacity. The inside diameter of the core sampler is $7.5 \mathrm{~cm}$ with a height of $15 \mathrm{~cm}$. Weight of the core sampling cylinder with moist soil is $2.81 \mathrm{~kg}$ and that with oven dry soil is $2.61 \mathrm{~kg}$. The weight of the core sampling cylinder is $1.56 \mathrm{~kg}$. Assuming $\pi=3.14$, the water depth in centimeter per meter depth of soil ( rounded off to two decimal places) is____________

Next Question :
An irrigation stream of $27 \mathrm{~L} \mathrm{~s}^{-1}$ is diverted to a check basin of size $12 \mathrm{~m} \times 12 \mathrm{~m}$. The water holding capacity of the soil is $15 \%$ and the average soil moisture content in the crop root zone prior to applying water is $7.5 \% .$ The depth of crop root zone is $1.2 \mathrm{~m}$ and apparent specific gravity of the soil is $1.5 .$ Assuming no loss due to deep percolation, irrigation time (in minute) required to replenish the root zone moisture to its field capacity is____________
