Water movement -: A cell to B cell

[@mukeshchandrakar7641]

Sir 1 pf is equal to how much cm of water

[@agriculturalstudies]

At 0 pF value, height of water column will be 1 cm.
1 pF value will be equal to 10cm of height of water column.
And 2 pF value will be 100cm of water column
And so on..
But at pF value of 2.53 height of water column will be 346cm ...
These values are mentioned in a table in the Book - D. K das.

Water move from A to B cell

[@agriculturalstudies]

Right 👍

[@johnorton4418]

​@@agriculturalstudieswhy? DPD is higher in B cell.

[@swastikamaity5631]

​@@johnorton4418 calculate from the formula
