What must be the height of a 200mm diameter vertical pipe carrying hot liquid so that the surrounding area becomes 38degrees C? Note that the rate of convection is 6 KWatts and the surface of the plate is around 90degrees C. answer in meters. (3 decimal places)
Final Answer must be a decimal or whole numbers only!!!
calculate the time it would take for K+ to diffuse 1 m if it has a Diffusion coefficient, DK+ = 2000 μm2/s. A larger spherical protein with radius, r = 3 nm, experiences a viscosity of 0.7 mPa s. How long would it take for this protein to diffuse 1 m if the temperature was 37 ̊C? (hint – use the Stokes-Einstein Relation)

- A digital system has been developed to measure temperatures in therange -20˚C to 100˚C. If the accuracy of the system is such that themaximum number of bits that it can represent is 10 bits, and the actualtemperature being read is 37˚C, what is the closest possible value thatthe system could represent? Interprete your results.arrow_forwarddT Newton's law of cooling states that the rate of change in the temperature T(t) of a body is proportional to the difference between the temperature of the medium M(t) and the temperature of the body. That is, = K[M(t) - T(t)), where dt Kis a constant. Let K= 0.04 (min)' and the temperature of the medium be constant, M(t) = 290 kelvins. If the body is initially at 352 kelvins, use Euler's method with h =0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes. (a) The temperature of the body after 30 minutes is 308.62 kelvins. (Round to two decimal places as needed.) (b) The temperature of the body after 60 minutes is kelvins.
