(b) What is the resting potential predicted by the Goldman equation?
(c) Explain whether space charge neutrality is satisfied.
(d) Explain why the equilibrium membrane potential does not equal zero.
(e) Explain why the resting potential does not equal the Nernst potential of any of the ions
A horizontal steel pipe having inner and outer diameter as 150 and 180 mm respectively is lagged with 50 mm thickness of 85% magnesia insulation inside ,which has flue gas flowing at 260oc
Mass of Air Required for Combustion of Fuel. A coal fired boiler uses fuel having the following analysis by mass:
Write down all the appropriate velocity boundary conditions for the flow around the bubble - Determine an appropriate form for the stream function.
A three-phase load, connected to a 440-V bus, draws 120 kW at a power factor of 0.85 lagging. In parallel with this load is a three-phase capacitor bank that is rated 50 k VAR. Determine the resultant line current and power factor.
At Chernobyl in 1986, hydrogen was produced by the reaction of superheated steam with the graphite reactor core: C(s)+H2O(g) yields CO(g)+H2(g) It was not possible to prevent a chemical explosion at Chernobyl
Design a suitable sieve plate for conditions below the feed point. Equilibrium data for the system ethanol-water, at 760 mmHg, mol fractions ethanol:
What concentration of phosphorus (P) would you expect at the top of the boule (X=0)? If the boule is 1 m long and has a uniform cross section,at what position (or Xvalue)would you expect the concentration of phosphorus to be twice as large as it is..
Determine mathematically the value and direction of a single resultant force which when acting upon the plate shown below would effectively replace the forces shown.
mole of oxygen in the exhaust gas per unit weight of fuel. e- mole of water vapour in exhaust gas per unit weight of fuel.
The average energy required to free an electron from the dynode surface is 10 eV. For each incident ectron released from rest, how many electrons are freed at the first dynode? At the last dynode?
Suppose that R2 is decreased to 0.5 min/ft2. Compare the old and new values of the ultimate gain and the critical frequency. Would you expect the control system performance to become better or worse, justify your answer.
