A potential flow source having an intensity of 10m2/s, placed in the point of Cartesian coordinates (1;0), and a sink having identical intensity, placed in the point (-1;0), are combined with a uniform flow at 25 m/s, in the direction -x (i.e., flowing from positive abscissae towards negative abscissae).
Find the width (in the x-direction) of the Rankine oval created by the flow, and the pressure difference between a point at infinite distance upstream and the point of coordinates (1,1).
Explain the Integral and Differential method of analysis for finding the rate of reaction.(May-2005)2.For the elementary reaction in series Ak1Rk2S if k1= k2and at t = 0, CA= CAoandCRo= CSo= 0, find the maximum concentration of R.
Obtain a discrete-time state-space model for the system with a sampling period T in terms of the model parameters.
The product from the trans alkylation reactor is returned to the benzene column. Sketch a block flow diagram of the process.
It is known that carbon from a living organism has a decay rate of 15decays=min g and that 14C has a half-life of 5730 years = 3:01 109 min. Find the age of the skeleton.
Which do you think would be the greater health hazard: the release of a radioactive nuclide of Sr or a radioactive nuclide of Xe into the environment? Assume the amount of radioactivity is the same in each case.
Then find the voltage across the 50-Ω resistor and the total power supplied by the source
Should the lease-and-flood arrangement be accepted? How should this proposal be presented to the company board of directors who understand and make it a policy to evaluate by discounted-cash-flow rate of return?
Here you compare the value of H when you use actual data (steam tables) and when you assume ideal gas. Reference means H = 0. State all reasonable assumptions. Vapor-liquid phase partitioning is involved.
Look up the boiling point of propane. What disadvantages are there to using propane instead of gasoline as a fuel?
How will the mole fractions of benzene and toluene in the liquid change with time (increase, decrease, or remain constant)? Explain your answer.
If this machine is operated from a 440-V dc supply, determine the speed at which this motor will run and the current taken from the supply, assuming no mechanical load, no friction and wind age losses, and that the field current is maintained at 4..
The laboratory division of your company has sent you the following data for the system n-pentane (1) propionaldehyde (2) at 35 °C: The activity coefficients of the two components at infinite dilution are 4.0 and the saturation pressures of the pur..
