Question

A U-tube is open on both ends and partially filled with water. Benzene (does not mix with water, density = 897 kg/m3) is poured into one arm forming a column of benzene 4 cm high. What is the difference in height between the two columns of water?

Answer 1

Answer:

0.459cm

Explanation:

Using

Po+ (L + h1) dBg= Po + Lx DW xg

So

h1= L( dw/dB-1)

= L( 1000/897-1)

= 4cmx 0.114

h = 0.459cm
