The diffusion constant of oxygen through water is an important limiting factor in the size of organisms that do not have active transport mechanisms to circulate oxygen through their systems. The diffusion constant or oxygen through water is 8 x 10-10 m2s-1. one average, how long does it take for an oxygen molecule to diffuse 1 mm through water?

    "The size of spherical aerobic bacteria is limited by the rate at which oxygen diffuses through water. A bacterium with a radius greater than roughly 10 micrometers is not able to obtain enough oxygen from the surrounding water to sustain itself. Given that the diffusion constant of oxygen in water is 8 �10^-10 m^2s^-1, how long does it take oxygen in water to diffuse an RMS distance of 10 micrometers?

    Oxygen diffuses from the surface of insects to the interior through tiny tubes called tracheae. An average trachea is about 2 mm long and has cross-sectional area of 2 times 10^-9 m^2. Assuming the concentration of oxygen inside is half what it is outside in the atmosphere calculate the diffusion rate J. The diffusion constant is 1.8 times 10^-5m^2/s. Express your answer to two significant figures and include the appropriate units.

    I need you to show the table Example 2 : Diffusion of Water Through Stagnant, Nondiffusing Air Water in the bottom of a narrow metal tube is held at a constant temperature of 20°C. The total pressure of air (assumed dry) is 1.0 atm and the temperature is 20°C. Water evaporates and diffuses through the air in the tube, and the diffusion path 22-Z is 0.5 ft long. Calculate the rate of evaporation at steady state in lb mol/hr.ft. The...

    Cells in a multicellular organism often signal to eachother by having specialized cells that emit signaling chemicals. Those signalling chemicals diffuse through the fluid medium in which the cells are embedded. Consider two cells that communicate by diffusing a chemical that has a diffusion constant D = 250 micro meters squared per second. The cells are a few micrometers in diameter. For simplicity, we will consider this a one-dimensional diffusion problem. a. Suppose that two of the signalling cells are...

    Question 3 (a) Water flows through a horizontal pipeline of constant 400 mm diameter in a water treatment plant. The pipe bends through a 70° angle. In order to design a thrust block for the bend, calculate the magnitude and line of action of the force exerted by the water on the pipe. The discharge through the pipe is 0.4 m/s. The water pressure at the inlet is equivalent to 22 m head of water. [10 marks] (b) Oil of...
