Heat is to be removed from a reaction vessel operating at 75°c by supplying water at 27°c and 0.12 kg/s through a thin-walled tube of 15-mm diameter. the convection coefficient between the tube outer surface and the fluid in the vessel is 3000 w/m2·k. (a) if the outlet water temperature cannot exceed 42°c, what is the maximum rate of heat transfer from the vessel, in °c? qmax= w (b) what tube length is required, in m, to accomplish the heat transfer rate of part (a)? l= m

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
