For laminar boundary layers it is reasonable to expect that δ /δt ≈ prn, where n is a positive exponent. consider laminar boundary layer flow over a flat plate with air at 100ºc and 1 atm, the thermal boundary layer thickness is approximately 15% larger than the velocity boundary layer thickness. determine the ratio of δ/δt if the fluid is engine oil (unused) under the same flow conditions. (round the final answer to two decimal place.) given: for air at 100ºc and 1 atm, pr = 0.7111. for engine oil (unused) at 100ºc, pr = 279.1

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
