liquid (L), it can be seen that the operating line is a simple y=mx+b equation. Therefore, with the point (xD,y1) and the slope (L/V), this operating line can be plotted.
The operating line is the, mole fraction of water (x) vs. partial pressure of water of H2SO4 (pa). The equilibrium line is the, mole fraction of water (x) vs. partial pressure of water of H2SO4 (pa) / the mole fraction of water (x).
The operating line equation is obtained by material balance around the column (as shown in Envelope 1 of the Figure above). The larger the distance between the operating line and equilibrium line, the larger the concentration difference for mass transfer, and thus, the easier the separation.
The operating line is a straight line with the slope (R / R+1) and the intercept (xD / R+1). The operating line can be plotted in the same way on the equilibrium curve to obtain the number of theoretical stages.
Opening a new credit card account could lower or hurt your credit score in the short term, because it requires a hard inquiry on your credit. The credit issuer will check your credit score and report when you apply for the account. This hard inquiry can cause the score to drop a few points temporarily.
Secured and Unsecured Lines of CreditA car loan is an example of a secured loan, in which the car itself serves as collateral. Like most credit cards, most personal credit lines have no collateral backing them, and so they are considered unsecured credit.
The BasicsUnlike a personal loan, there is no set schedule to repay the money you borrow from a line of credit. However, you must make monthly interest payments on any amount you borrow; interest begins to accrue the very first day you borrow the money until the day you pay it back.
Because you can usually get a line of credit at a lower interest rate than your credit card, using a line of credit to pay off credit card debt can reduce your total interest costs and reduce the amount of time you're in debt.
By and large, lines of credit are not intended to be used to fund one-time purchases such as houses or cars—which is what mortgages and auto loans are for, respectively—though lines of credit can be used to acquire items for which a bank might not normally underwrite a loan.
If you're struggling with financial problems and can get approved for a line of credit, then it's worth getting one. You can pay off your debts and escape the worst when it comes to your finances. However, beware of using a line of credit to buy a car.
Compared to credit cards, lines of credit typically offer higher credit limits compared. If you need a higher credit limit, then a line of credit may be a better option than a credit card. A less stringent repayment schedule is needed.
There is no formula for the monthly payment amount. The lender determines payment size based on factors such as the interest rate, outstanding balance and terms of the line of credit. Calculating interest on line-of-credit payments is usually done using the average daily balance method.
There are 4 main types of personal loans available, each of which has their own pros and cons.
- Unsecured Personal Loans. Unsecured personal loans are offered without any collateral.
- Secured Personal Loans. Secured personal loans are backed by collateral.
- Fixed-Rate Loans.
- Variable-Rate Loans.

Keep in mind, if you don't have good personal credit, you may find that qualifying for a line of credit is more difficult. Also, while lines of credit can often be cheaper than credit cards, you could possibly qualify for a personal loan with a lower interest rate.
You can use a line of credit for just about anything – think holiday, home renovations or even a new car. Best of all, you only pay interest on the amount you've borrowed, not your entire credit limit.
Here's how it works: Step 1: Make the minimum payment on all of your accounts. Step 2: Put as much extra money as possible toward the account with the highest interest rate. Step 3: Once the debt with the highest interest is paid off, start paying as much as you can on the account with the next highest interest rate.

Mortgages tend to have unfavourable interest and compounding structure, making them the better bet to pay down first. Lines of credit have more simple interest calculations, making them easier to pay down over time. I have clients who have taken out lines of credit to pay off their mortgages, once they got low enough.
To access money from a line of credit, you may:
- write a cheque drawn on your line of credit.
- use an automated teller machine ( ATM )
