The geopotential height in troposphere is given by __________(a) H=\(\frac{T_0}{l_0}\)[(\(\frac{p}{p_0}\))^\(\frac{-L_0R}{g_0}\)+1](b) H=\(\frac{T_0}{l_0}\)[(\(\frac{p}{p_0}\))^\(\frac{L_0R}{g_0}\)-1](c) H=\(\frac{T_0}{l_0}\)[(\(\frac{p}{p_0}\))^\(\frac{-L_0R}{g_0}\)-1](d) H=\(\frac{T_0}{l_0}\)[(\(\frac{p}{p_0}\))^\(\frac{L_0R}{g_0}\)+1]This question was addressed to me during an online interview.My query is from Measurement of Height in division Atmosphere and Air Data Measurement of Aircraft Performance

Answer»

The correct OPTION is (c) H=\(\frac{T_0}{l_0}\)[(\(\frac{P}{p_0}\))^\(\frac{-L_0R}{g_0}\)-1]

For EXPLANATION I would say: The geopotential HEIGHT in TROPOSPHERE is given by H=\(\frac{T_0}{l_0}\)[(\(\frac{p}{p_0}\))^\(\frac{-L_0R}{g_0}\)-1] where

H=geopotential height

R=characteristic gas constant

T0=temperature at 11km

P0=pressure at 11km

g0=acceleration due to gravity

p=pressure

L0=lapse rate.
