Water is used to remove CO$_2$ from the air by absorption in a column packed with Pall rings. At a certain region of the column where the partial pressure of CO$_2$ in the gas phase is 12.0 bar and the concentration of CO$_2$ in the bulk liquid is negligible, the absorption rate of CO$_2$ is 2.5 ×10$^{-6}$ mol/cm$^2$-s. The diffusivity of CO$_2$ in water is 2.0×10$^{-5}$ cm$^2$/s and Henry's law constant for CO$_2$ is 620.5 bar ($p_A$ = 620.5$x_A$). The molecular weight and density of water are 18.01 g/mol and 0.997 g/cm$^3$ respectively. (a) How much is the overall mass transfer coefficient, $K_x$ based on the liquid phase? (b) If the liquid film thickness at the interface is $l$=6.0×10$^{-3}$ cm, how much is the liquid-film mass-transfer coefficient $k_x$ based on mole fraction? (c) How much is the gas-film mass transfer coefficient $k_p$ based on pressure

(Problem 17.8 from Textbook) A person at age 30 is planning for retirement at age 60. He projects that he will need $100,000 a year, disbursed a yearly basis, until age 80. Determine the uniform annual contribution (by him and his company) needed to provide these funds. Assume that the effective interest rate is 8\% yr$^{-1}$ and the rate of inflation is zero. Question 1 1 pts If the person is will need $100,000 a year, disbursed a yearly basis over 20 yr, calculate the worth of the money at retirement. Question 2 1 pts Now, determine the annual contribution needed, so that the retirement fund will accrue to the amount calculated above.

The bookkeeper misplaced the bank statement for May 2021 but had already identified the differences between the Bank Statement and the Financial records and this is reflected as follows: 1) In the general ledger bank account the following details have be identified: a. May cash receipts amounting to R904 323, b. May cash payments amounting to R715 017. 2) Included in the cash receipts for May 2021 is an amount of R80 343 which was received but was not reflected on the bank statement. 3) Differences between the business' accounting records and the bank statement the following was noted: a. The May bank statement included a debit amount of R153 for the monthly bank charges. b. The May bank statement reflected an EFT from a customer for R90 900 which was not recorded in the accounting records. c. The May bank statement reflected all payments recorded in the financial records except for the following three payments which have not yet been presented to the bank for payment: i. Cheque no. 138 for R17 222 ii. Cheque no. 250 for R12 800 iii. Cheque no. 266 for R6 021 d. All transactions in the accounting records have been correctly recorded however on examination of the bank statement it was discovered that cheque no. 231 for R17 600 was recorded as debit of R10 760 on the bank statement. e. A payment received from a customer, Mr Broke, for R6 300 was received and recorded in the accounting records, however, the deposit on the bank statement was marked: \"Returned to drawer\" as Mr Broke had insufficient funds. You are required to: a) Record all the relevant transactions in the General Ledger Bank Account of the business. (7 Marks) b) Using the information above, calculate the bank statement balance at the end of May (11 Marks) 2021.
