Given that the reaction for fresh feed A and B is2A + 5B ------> 3C + 6Din a reactor with recycle, find the desired recycle ratio (moles recycled/moles fresh feed) if in the fresh feed A is 20% in excess, the once through conversion of B is 60%, and the overall conversion of B to products from the overall process is 90%. After the products exit from the reactor, a stream of pure B is separated from the products and forms the recycle. Assume 1 mol of B in the feed as a basis.
A wire carrying a current is shaped in the form of a circular loop of radius 4.0 mm. If the magnetic field strength at its center is 1.1 mT with no external magnetic fields contributing to it, what is the magnitude of the current that flows throug..
The space between the plates is then filled with a dielectric material, with dielectric constant k = 6.55. What must the magnitude of the charge in micro coulombs on each capacitor plate now be, to produce the same potential difference between the..
The lamp is then inserted in a DC circuit and it is noticed that as the voltage increases the resistance also increases. How do you explain this apparent contradiction with Ohm's law Why does the lamp resistance increase with voltage
Consider a satellite communication link with a one way propagation delay of 300ms between the sender and receiver, operating at 10Mbps using packets of length 1500bytes. Length of the ACK packet is also 1500 bytes.
As speed increases, the lower lamp, L1 lights, then L1 and L2, then, L1, L2, and L3, until all lamps light at the highest speed. Once all the lamps illuminate, no further increase in speed will have any effect on the display.
In a multiuser CDMA system of DSSS, all transmitters are at equal distances from the receivers. The additive white Gaussian noise density Sn(f) = 5x10^-7 W/Hz. BPSK is used by all users with bit rate = 16 kb/s. There are 16 users.
A small gasoline engine can put out 24,000 N-m/min of mechanical power. The engine is used to drive an electrical generator that is 70 percent efficient. 1 N-m = 2.78 X 10-4W-h. Find the output of the generator in Watts.
Then find the total energy stored in the battery before it is connected to the bulb. Determine the total amount of charge that has pessed through the wires that connect the battery and the bulb.
Construct the RC differentiator. Set the channel 1 input coupling switch to dc. Next adjust the dc offset, amplitude, and frequency controls of the function generator to produce the input waveform.
Determine whether the system described by (1) y[n]=log(nx[n]), (2) y[n]=sqrt(n)*x[n+1], (3) y[n]=x[n-2]u[n], where a is an integer and |a|>1, is (i) memoryless; (ii) invertible; (iii) causal; (iv) stable; (v) time invariant; (vi) linear
A conducting bar of length l rotates about one end in a uniform magnetic field at a frequency of ω rad/sec. Determine the potential difference between the two ends using (a) Faraday's law of induction.
Design a circuit which realizes this filter using Sallen-Key configuration. Find all the values of the circuit elements and determine the DC gain. For sake of easy availability of parts to build the circuit, chose the capacitors needed to be 0.01..
