Use a one-dimensional analysis of the diffusion of oxygen into a layer of adherent cells to show that the maximum oxygen delivery per unit area (Noxmax) in Example Problem 7.7 is given by
where C is the saturation concentration of oxygen and R is the thickness of the liquid layer
Example Problem 7.7
How are specific oxygen uptake rates measured?
An experimentalpackage and its support structure wh ich are to be place on board a space station act as an underdamped spring - mass system w ith a force constant of 2.1X106N/mand mass 108kg. Does this package meet the requirement
A three-phase, four-wire system operating with a 208-V line voltage is shown in Fig. 12.64. The source voltages are balanced. The power absorbed by the resistive wye-connected load is measured by the three-wattmeter method.
We have four 3-H inductances. What is the maximum inductance that can be obtained by connecting all of the inductances in series and/or parallel What is the minimum inductance
When attached to adirect current supply of 120V. What value of current does each bulb draw What is the total current drawn by the bulbs If one bulb burns out, does the current through eachremaining bulb increase, decrease or remain the same
inductor L and assume they have been connected for Consider a circuit consisting of a sinusoidal source V s (t) = cos (t) u (t) volts connected in series to a resistor R and an a very long time.
Given a fiber optics line between Alaska and Oregon, with a data capacity of 2.5 Gbits/s, calculate the following: a. the number of voice channels (64 kbits/s each) that can be carried on this line b. the number of CDs per second (650 MB each) that c..
The exponential Fourier series coecients for a signal x(t) are: ak= { 1.57 when k=0, 0 when k is even and k doesnt equal 0, ((-1)(k-1)/2)/k when k is odd} Determine the following: (a) Plot the spectrum of the Fourier series.
In an FM line of sight link , the frequency is 6 GHz and the beamwidth = 27 MHz the transmitting and receiving antennas have a gain of 33 dB , the receiving antenna is 40 Km apart from the transmitting station
10 mH inductor, 4.7 µF capacitor, and 68 Ω resistor in series with a 5 V AC source running at 1kHz. How would we find these three power values?
(a) Calculate on the axis of a charged ring. The ring lies in the z = 0 plane, has radius a, and carries uniform charge density λ C/m. (b) Repeat for a charged disk. The disk lies in the z = 0 plane, has radius a, and carries uniform charge density ..
a. What is the range of the sensor voltage outputs initially and finally? b. What range of voltages would be expected to be measured 2 sec after the step change is applied?
If one of the normal vectors to an interface is n-hat = 1/sqrt(13) (3x-hat + 2z-hat) and the electric field just below the interface is E1 = 9x-hat + 2y-hat + 2z-hat, what is the vector part of E1 normal to the interface
