The initial moisture content and the equilibrium moisture of a granular paste material extruded into cylinders (diameter- 5.25 mm, length-20 mm) is 0.8 k? h2okg dry solid and 0.015 kg h20/kg dry solid respectively. the cylinders are packed on a screen to a depth of 65.8 mm. the true solid density is 1580 kg/m2. the bulk density of the dry solid in the bed is 650 kg/m3 air (wet bulb temperature 48c and humidity 0.06 kg h2o/ kg dry air) passes through the bed with a superficial velocity of o.75 m/s. the total critical moisture content is 0.60 kg h20/kg dry solid calculate (i) the time of drying for the constant-rate period (s), (ii) the time of drying for the falling-rate period (s) and (ii) the total time to dry the solids to 0.3 kg h20/kg dry solid (s).

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

if you're asking what comes out, it's steam.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
