A helium-filled balloon at atmospheric pressure is tied to a 3.4 m long, 0.060 kg string. The balloon is spherical with a radius of 0.40 m. When released, it lifts a length (h) of the string and then remains in equilibrium as in Figure P9.78. Determine the value of h. When deflated, the balloon has a mass of 0.25 kg.

2. Relevant equations

Bernoulli's equation

A1V1=A2V2

P = Po + (density)gh
