Solution

Introduction

Nutrients dissolved in water are carried to upper parts of plants by tiny tubes  due to the capillary rise. Capillary rise is the ability of a liquid to flow in narrow space without the assistance of, or even opposition to external forces like gravity.

Step 1

        Given ,The temperature of  the  water solution , T=200 C

        Diameter of the capillary tube, D =0.002 mm and the diameter of the tube is constant.

        The contact angle is 150

        We know that ,

        The surface tension of the water at  200 C, σs =0.073 N/m

        The density of the water solution  ρ =1000 kg/m3
