Jonathan "John" I.Q. Neidelbaum Frink, Jr., B.Sc., Ph.D. M.R.S.C., C.Chem, better known as Professor Frink and once referred to as Doctor Frink, is Springfield's 40-year-old local scientist and college professor, and is extremely brilliant, though somewhat socially inept. Frink often tries to use his bizarre inventions to aid the town in its crises, but they usually only make things worse.
Frink is Springfield's local mad scientist. He has a trademark mannerism of using tourettes-like gibberish when excited, such as "GLAYVIN!" and shouting other words that have no relevance to the situation at hand. He also occasionally refers to the importance of remembering to "carry the one" in various mathematical calculations. He is almost never seen without his glasses and has only taken them off once.
Frink is said to have an IQ of 197; 199 before he sustained a concussion during the collapse of Springfield's brief intellectual junta. He is a member of the Springfield Mensa and a college professor at Springfield Heights Institute of Technology.

Apple juice is being concentrated in a single effect evaporator. At steady-state conditions, dilute juice is the feed introduced at a rate of 0.67 kg/s. The concentration of the dilute juice is 11% total solids. The juice is concentrated to 75% total solids. The specific heats of dilute apple juice and concentrate are 3.9 and 2.3 kJ/kg*K. The steam pressure is measured to be 304.42 kPa. The inlet feed temperature is 43.3°C. the product inside the evaporator boils at 62.2°C. The overall heat transfer coefficient is assumed to be 943 W/m2*K. Assume negligible boiling point elevation. Calculate the mass flow rate of concentrated product, steam requirements, steam economy and the heat transfer area.
Mass flow rate of steam = _ . _ _ _ kg/s
Heat transfer area = _ _ . _ m^2
A = last digit of mass flow rate
B = last digit of heat transfer area - 2
C = second digit of mass flow rate
A new food product in a can is being sterilized in a retort. Can dimensions are 75 mm in diameter and 110 mm in height. The thermal conductivity of the food is 0.5 W/m*K, its density is 0.95 g/cm3 and its specific heat is 3.8 kJ/kg*K. The steam temperature in the retort is 121°C and the food is initially at 4°C. The efficiency of the retort means that there is negligible surface resistance to heat transfer. What is the temperature at the geometric centre of the can after 30 min of processing?
Bi-1 = _
Fo = _ . _ _ _ (infinite cylinder)
Fo = _ . _ _ _ (infinite slab)
Temperature at centre of can in 30 min = _ _ °C
D = second digit of Fo (infinite cylinder)
E = Bi-1
F = first digit of can temperature after 30 min - 1
G = last digit of Fo (infinite slab) - 1
