Answer:
h = 1.22 m
Explanation:
Given:
Pressure in the vein = 12200 Pa
Specific gravity of the liquid = 1.02
now,
the pressure due to a fluid is given as:
P = pgh
where,
P is the pressure,
ρ is the density of fluid = specific gravity x density of water = 1.02 x 1000 kg/m³
ρ = 1020 kg/m³
g is the acceleration due to the gravity = 9.81m/s²
h is the height
thus,
h = P/pg =
The heat transferred by the steam to the skin is given by
where
m is the mass of the steam
is the latent heat of vaporization.
In our problem, the mass of the steam is (converting into kg)
while the latent heat of vaporization of the steam is
Substituting into the previous formula, we find the heat transferred to the skin:
