In order to define the local hydraulic resistance (Î´P1) the Weisbach formula is used. (3) where Î¶ is the coefficient of local resistance. For flow in smooth channels the friction factor f depends on the flow conditions and is only a function of Re = Å«DH/Î½.
Plant cells can be larger than animal cells. The normal range for an animal cell varies from 10 to 30 micrometers while that for a plant cell stretches from 10 to 100 micrometers. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
The main difference is that the plant kingdom has cell walls, and the animal kingdom doesn't. Plants use photosynthesis to create energy from sunlight, while animals use metab â¦ olism to create energy from food.
