Question

The manometer shown below is used to measure the difference in water level between the two times calculate the difference for the conditions indicated​

Answer 1

Answer:

Explanation:

Your answer is attached

Answer 2

Answer: 4 cm

Explanation:

P(a) + h(1)ρg - 40ρ(1)g + 40ρg = P(a) +

h(2)ρg

h(2)ρg - h(1)ρg = 40ρg - 40ρ(1)g

As ρ(1) = 0.9p

(h(2) - h(1))ρg = 40ρg - 36ρg

h2 - h1 = 4cm
