What are the two main functions of food in an animals body?

On a per-kilogram basis, why does a small mammal such as a shrew require so much more energy than does an elephant or other large mammal?

A solution at 107 C contains 50 mol% water (W) and 50 mol% formic acid (F). Using (2-72) with vapor pressure data and the van Laar equation with AWF = -0.2935 and AFW = 0.2757: (a) Compute the...

A test leaf filter is used to determine the filtration rate for an unclarified broth from a fermentor. At a pressure drop of 50 kPa, 150 mL of filtrate are collected in 30 minutes. If the resistance...

A 6-inch demister pad is to be used to separate liquid entrainment from a gas in a horizontal flash drum. Calculate the demister diameter using the following data: Vapor flow rate = 465 cfm at 110F...

For a solid, spherical particle of 0.8 mm in diameter and a density of 2,600 kg/m 3 that is immersed in a fluid of density 1,200 kg/ m 3 and a viscosity of 1.0 cP, calculate (a) The unhindered...

Fifty wt% methylcyclohexane (MCH) in n-heptane is fed to a countercurrent, stage-type extractor at 25 C. Aniline is the solvent and reflux is used at both ends of the column. An extract containing...

Liquids A and B, which have nearly identical boiling points, are to be separated by liquidliquid extraction with solvent C. The following data represent the phase equilibrium at 95 C. Determine the...

In Examples 15.13 and 15.18, benzene is adsorbed from air at 70 F in a 6-ft-high bed of silica gel and then stripped with air at 145F. If the bed height is changed to 30 ft, the following data are...

CaCO 3 precipitate can be produced by reaction of an aqueous solution of Na 2 CO 3 and CaO, the byproduct being NaOH. Following decantation, slurry leaving the precipitation tank is 5 wt% CaCO 3 ,...

A slurry is passed through a filter cloth 0.02 m 2 in area at a constant rate, with 4 x 10 5 m 3 /s of filtrate being collected. After 100 s, the pressure is 4 x 10 4 N/m 2 ; after 500 s, it is 1.2 x...
