The monthly saving P that has to be deposit in a saving account that pays an annual interest rate of r in order to save a total amount of F in N years can be calculated by the formula: P = F(r/12) (1 + r/12)^12N - 1 Calculate the monthly saving that has to be deposit in order to save $100,000 in 5, 6, 7, 8, 9, and 10 years if the annual interest rate is 4.35%. Display the results in a two-column table where the first column is the number of years and the second column is the monthly deposit. The variation of vapor pressure p (in units of mm Hg) of benzene with temperature in the range of 0 < T < 42 degree C can be modeled with the equation: ln (p) = k/.0101 a - b where a = 34172 and b = 7.9622 are material constants and T is absolute temperature (K). Write a program that calculates the pressure at various temperatures and displays the results in a three column table. The first column must be temperatures in degree C, the second column, temperatures in K and the third column is the corresponding pressures in mm Hg. Include title and header information for each column.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
