Chapter 9, Problem 3RQ

Question: Based on the given problem, create an algorithm and a block diagram, and write the program code: Function: y=xsin⁡x Interval: [0,π] Requirements: Create a graph of the function. Show the coordinates (x and y). Choose your own scale and show it in the block diagram. Create a block diagram based on the algorithm. Write the program code in Python. Requirements: Each step in the block diagram must be clearly shown. The graph of the function must be drawn and saved (in PNG format). Write the code in a modular way (functions and the main part should be separate). Please explain and describe the results in detail.

Enthalpy and equilibrium data for the mixture at 1 atm are given in Table Q2 below. Ask an expert (a) Devise a procedure, using the enthalpy-concentration diagram, to determine the minimum number of equilibrium trays for the condition of total reflux and the required separation. Show individual equilibrium trays using the the lines. Comment on why the value is Independent of the food condition.

You are working with a database table that contains customer data. The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country.  You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.
