A well flowing 40%water(viscosity=0.5cP, and FVF=1) and 60% oil(viscosity=4cP and FVF=1.5 from 30-ft thick reservoir. Core analysis indicate the permeability to be 305md. Estimate the productivity index of this well. Assume relative permeability to 0.25 for oil 0.15 for water.

how to calculate the maximum load voltage of 3 phase halve and full wave rectifier

Two liquid streams are pouring in a container, 8 in. diameter and 15in. high. The mass flow rate of stream A is 1.2 lb/sec and the volume flow rate of B is 0.035 ft3/s. If the specific gravities of A and B are 1.1 and 0.9, respectively, What is the gage and absolute pressure at the bottom of the filled tank in psia.

Draw the profile of a cam in which the follower moves with simple harmonic motion during ascent while it moves with uniform velocity motion during descent. The other data is as follows.

Least radius of cam = 50mm; Angle of ascent = 480; Angle of dwell between ascent and descent = 420; Angle of descent = 600; Lift of follower = 40mm; Diameter of roller = 30mm; If the cam rotates at 360 r.p.m. anticlockwise, find the maximum velocity and acceleration of the follower during descent.

Q). The unique addresses assigned to the four registers (R1,R2,R3,R4) of the I/O interface are equal to the XX3 , XX7 , XXB and XXF in Hex . Where XX is hex digits equal to your 82 .Show the well labeled external circuit that must be connected between and 12-bit I/O address from the CPU and the CS, RSI, and RS0 Inputs of the Interface

Q) Find the values of the flags (carry ,sign ,zero, overflow) of the processor status register for the given example of two 16 bit no’s in Hex (ABCD + 5678) and draw the circuit diagram also

Q) Explain the difference between RISC and CISC in detail ?

Q)Explain the Register stack organization of 64 locations of stack(0 to 63). take the initial value of the stack pointer is SP = 1F in Hex. Explain the following push and pop instructions through the Register stack organization diagram.

(1) PUSH R9 WHERE R9 = (82) Hex

(2) POP R8 WHERE R8 = (82 + 5 ) Hex for example roll no 64 is having the data in R9 = 64 Hex and R8 is ( 64+5 = 69 Hex)

1. Design a circuit of General register organization in which 2 registers are there from R0 to R1. (a) Perform the following microoperation and explain the operation in the steps through the diagram properly: - SUB R0 ,R0 ,R1 .

(b) Explain the control word as per the register configuration given above

The unique addresses assigned to the four registers (R5, R6, R7, R8) of the I/O interface are equal to the XX3, XX7, XXB, and XXF in Hex. Where XX is hex digits equal to your roll no. (if the student is having to roll no 45 then addresses are 453,457 ,45B, 45F in Hex ) .Show the well-labeled external circuit that must be connected between the 12-bit I/O address bus from the CPU and the CS, RSI, and RS0 Inputs of the Interface.
