· CORRECT METHOD:
· INCORRECT METHOD:  p2 = (W * a)/g + p1 = a^2 - Ap – μ = 0
Part2 (40 points) 
Either in class open-book or take-home (to be release one lecture before the midterm in that case) 
Problem 1 
The specific gravity of benzene is 0.876. Calculate its specific weight and its density in U.S. Customary System units. 
Given specific gravity of benzene is 0.876
Specific weight of benzene is given by the following equation
Where γ is specific weight, ρ is density of the substance and g is acceleration due to gravity. 
From the given specific gravity, 
the specific density of benzene = 0.876 x 1000 kg/m3 = 876 kg/m3
Acceleration due to gravity g = 9.81m/s2
Hence the specific weight of the benzene = 876 x 9.81 kg/m3 * m/s2 = 8593.56 N/m3 =8.593kN/m3
Problem 2 
If milk has a specific gravity of 1.08, what is the pressure at the bottom of a milk can 550 mm deep? 
Specific gravity of milk =1.08
Density of the milk = 1.08 X 1000kg/m3 =1080 kg/m3
The depth of the can = 550mm = 0.55m
The pressure at the bottom of the milk can,
P = ρ*g*H
P = 1080x 9.81 x 0.55 = 5827.14 N/m2 =5.827 kPa
Problem 3 
For the differential manometer shown, calculate the pressure difference between points A and B. The specific gravity of the oil is 0.85.
From the given specific gravity of oil, its specific density = 0.
