Transpiration Rate Calculator

💧 Diffusion, osmosis & transport. Use the Transpiration rate (mass loss) formula to find rate, mass lost, time: pick the value you want, type the others, and the answer updates as you go.

rate=mass losttime\text{rate} = \dfrac{\text{mass lost}}{\text{time}}
Rate0.25 g/h

Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.

Worked example

Find the rate when Mass lost = 1.5 g, Time = 6 h.

Using rate = (mass lost)/time: Rate = 0.25 g/h.

Frequently asked questions

What is the formula for Transpiration rate (mass loss)?

rate = (mass lost)/time.

What do the letters stand for, and what units are used?

Rate in g/h, Mass lost in g, Time in h.

How do you calculate rate?

Put the values into rate = (mass lost)/time. For example, with Mass lost = 1.5 g, Time = 6 h, rate = 0.25 g/h.

Can I solve for a different value?

Yes. In the calculator above, pick the circle next to any value (rate, mass lost, time) and fill in the others: it rearranges the formula for you.
