    I want to resolve to the degree of saturation of a salt solution

    I want to measure salt brines. I can measure specific gravity and degrees Fahrenheit. I need a formula that I can insert the two measured values into and get the degree of saturation of my brine. I can't find a formula. I'm not sure a formula exists, but I can't understand why not. There are...

    Significance of the Saturation Photon-flux Density

    Homework Statement In the general two-level atomic system of Fig. 14.2-3, τ2 Significance of the Saturation Photon-flux Density. In the general two-level atomic system of Fig. 14.2-3, τ2 represents the lifetime of level 2 in the absence of stimulated emission. In the presence of stimulated...

    CO2 Saturation Point: Effect as Greenhouse Gas

    can anyone tell me what the saturation point of CO2 is in the atmosphere in relationship to it's effect as a green house gas? At what point does extra CO2 have no more effect?

    Troubleshooting Opamp Saturation in Orcad Pspice 9.2

    Hello Everyone, I am trying to model a circuit using Orcad Pspice 9.2 I am trying to solve the time when the opamp saturates with maximum voltage operation of 10v and -10v. I am applying different voltages to the circuit, when I do the transient analysis, i am not getting the right time. For...

    MS Excel Help - Saturation Points ?

    MS Excel Help -- Saturation Points ?! Does anyone know how to do this with if-then statements or something else? For example: I want to analyze inflow and outflow in a tank, when the volume reaches zero then it's empty of course--so I shouldn't have a negative volume after this, volume...

    Magnetic Saturation in Solenoids: Core Size & Shape Impact?

    Magnetic Saturation?? In a solenoid, does the magnetic field strength at which a core, in this case iron, begins to saturate change relative to the core's size or shape? Or is it constant for the material of the core, regardless of other factors? in other words will the core begin to saturate...

    Gain saturation in laser cavity

    Im studying gain saturation for homogeneous and inhomogeneously broaded transitions. Im a little confused bout the logistics of laser operation regarding the gain in the cavity. So from ground state, the atoms are optically pumped to produce population inversion(4 level system) where...

    Finding the Saturation Current of a photodiode in Reverse Bias

    Homework Statement I am trying to finish the equation, to compare it against a set of data so I can then find the accuracy of my results in relation to the equation: I(dark) = I(sat) * e(qV/kT) -1 I have the following data: Va - the applied (bias) voltage q kB - Boltzmann Constant...

    Air saturation level vs temperature and pressure

    Here is my problem: I got an open cylinder of constant volume V that is been closed at 40'C and 100% R.H. The cylinder when closed is completely sealed. Inside the cylinder there is and heater that bring temperature at 60'C. When that temperature is reached, I see condensation inside the...

    Explaining BPS Saturation in Superalgebras

    I've tried searching, but without much luck. Can someone please explain what it means for a state to be BPS saturated? It's in relation to a superalgebra \{ Q_{a},Q_{\dot{a}} \} = W \delta_{a\dot{a}} and then the mass of a particle satisfying M \geq \frac{c_{1}}{\lambda}|W| where lambda is the...

    How Does Overvoltage Affect Transformer Core Saturation and Current Flow?

    I'm trying to understand what happens to a distribution transformer in relation to overvoltage conditions (in terms of saturation and current flow; not insulation failure). I understand that once the voltage has risen high enough to drive the magnetic core past the saturation point, that the...

    How Does Surface Curvature Affect Saturation Vapour Pressure?

    The pressure exerted by a saturated vapour depends on the temperature and the curvature of the liquids surface. Why does it depend on the curvature of the liquids surface?

    Explaining Nuclear Force Saturation: The Role of Helium Nucleus Stability

    I have solutions to a past paper essay question that indicates that the student should explain the saturation of the nuclear force in terms of the stability of the helium nucleus. I do not see how to do this, I can only explain the saturation of the force in that the nuclear biniding energy is...

    Understanding Saturation Current and the Role of 'ni' in a P-N Junction Equation

    In the equation for saturation current in a p-n junction there is an 'ni' term. Anyone know what that represents. Can't seem to find it anywhere.
