Space time equals the mean residence time
WebIf x and y are String references and if x.equals(y) is true, then x == y is true. If x, y, and z refer to instances of wrapper classes and x.equals(y) is true, and y.equals(z) is true, then z.equals(x) will always be true. If x and y are String references and x == y is true, then y.equals(x) will be true..... WebMean residence time is equal to the space time, when A. The feed rate is measured at temperature and pressure in the reactor B. The temperature, pressure and the density of reaction mixture remains constant throughout the reactor C. There is no change in number of moles in gaseous reaction D. All of the above Answer: Option D Join The Discussion *
Space time equals the mean residence time
Did you know?
WebThe mean residence time or mean transit time, that is the mean age of all the particles leaving the control volume at time t, is the first moment of the residence time distribution: … Web2. apr 2024 · Consequently, the space time is the same as the average residence time in a batch reactor. Is residence time same as space time? Space Time – For no …
WebSpace time corresponds to the average residence time in an isothermal CSTR. In the steady-state CSTR, the net rate of production is equal to the difference between the outlet and … WebMean residence time is equal to the space time, when: A. the feed rate is measured at temperature and pressure in the reactor. B. the temperature, pressure and the density of reaction mixture remains constant throughout the reactor. C. there is no change in number of moles in gaseous reaction. D.
WebThe graph is the distribution of residence times about the mean. The bottom line of output gives us the integral of the PDF, the mean normalized residence time, the concentration of A and B and, finally, the conversion of A. We see from this graph that with the mean residence time of 100 and variance of 2, this appears to be a sharp distribution. Web20. sep 2010 · When one seeks to calculate only the mean residence time and not its full distribution, this “residence time equation” constitutes a significant simplification over the …
