Concept Introduction:
Fahrenheit scale: The Fahrenheit and Celsius scale is similar to converting between different unit of length or volume, but is a bit more complex because two correction need to be made one to adjacent for the difference in degree size and one to adjacent for the difference zero points. The degree size correction is made by using the relationship
Rankine scale: It is similar to the Kelvin scale in that zero is absolute Zero; however, a degree Rankine is defined as equal to one degree Fahrenheit as opposed to one degree Celsius (as used by the Kelvin scale). The respective temperature of

- A flat (not spherical) tissue engineered skin (thickness 3.9 mm) is attached to the bottom of a dish and cultured with cell media atop it (which has an oxygen concentration of 0.15 mol/m3). The diffusivity of oxygen in the skin is 3.2 E-9 m?/s, and according to experiments that you've performed, you want to make sure that the concentration of oxygen in the device doesn't fall below 0.06 mol/m3. (Below that concentration harms the cells.) The rate of oxygen consumption is -5 E-17 mol/[cell•s]. What is the maximum cellularity (in cells/mL, three significant digits) that this tissue engineered skin can support?arrow_forward140 120 Super- critical A 100 fluid CO,(s) Co,(1) 80 Critical point 30.98°C, 60 72.79 atm 40 В 20 CO>(g) Triple point - 56.57°C, 5.11 atm -80 -60 -40 - 20 20 40 Temperature (C) Above is the phase diagram of CO2.
