A process has a distillation column, where a crude dichlorobenzene is pumped from a storage tank. Nitrogen is used to blanketing the column and the pressure above the liquid surface is held constant at 0.1 bar gauge pressure. The minimum depth of liquid in the tank is 1 m. The distillation column operates at a pressure of 500 mmHg. The feed point to the column is 16 m above the base of the tank. The tank and column are connected by a 50 mm internal diameter commercial steel pipe, 220 m long. The pipe run from the tank to the column contains the following valves and fittings: 20 standard radius 90° elbows: two gate valves to isolate the pump an orifice plate and a flow-control valve. If the maximum flow-rate required is 20,000 kg/h, calculate the pump motor rating (power) needed. Take the pump efficiency as 70 per cent and allow for a pressure drop of 0.5 bar across the control valve and a loss of 10 velocity heads across the orifice. (Density of the dichlorobenzene 1300 kg/m3, viscosity 1.4 cp).

If a consumer is consuming two commodity X and Y and his utility function U(X,Y)=2xy+6.if the price of the two commodity are 2 and 6 respectively, and consumer has a total income of 80 birr to be spent on the two goods,a)find the utility maximizing Quantity of good X and Y (b) find the MRSxy at equilibrium (c) find the MRSyx at equilibrium

Polynomial

Ms. Seena has brought 10 items and she wants to print the item with minimum and maximum cost. Write a software program to do it. 


Write a function that draws a circle on the coordinate plane.


The MATLAB function should use a,b r inputs, where a and b are the x-axis and y-axis coordinates of the center of the circle and the radius being r.


Add the labels to axes and annotation (a,b) at the center of the circle.


(use the parametric equation of a circle).


Write a c++ program that asks user to input starting and ending number of range. if the ending number is greater than starting number show the range input by user and display the following 1)sum of the even number between the range, 2)sum of all odd number between the range, 3)count how many numbers are present between the range, 4)how many numbers between the range are either divisible by 05 or 10, 5) if there is number "1000" present between the range, the ending number should change to 1000 and then should break, 6)average of all numbers between the range?

if the ending number is not greater than starting number show you entered an invalid range.
