Hi Scientists and Engineers,

I would like to ask the following question I have about fluid flow. I have tried doing a force balance on it and I have also used Bernoulli's equation but to no avail.I just want to know if I'm tackling this problem in the right way or if I don't please help me. I was only given the density of mercury at 13600kgm^-3.

Saturated steam at 2 bar enters the top of a sealed cylindrical cavity and condenses, forming a pool of condensate. At the bottom of the cylinder is an exit pipe of diameter 5 cm. This exit pipe is open to the atmosphere, which consists of air at 1 bar. A cone of mass 1 kg blocks this exit, preventing any condensate from draining from the cylinder. The height of the cone that protrudes into the drain is 5 cm.

The volume of a cone of height H and base radius R is πR2H/3.

A manometer which is open to the atmosphere contains 50 cm of mercury. If the condensate level h is equal to 10cm, what is the height of the water level in the manometer with respect to the condensate level (i.e. in the diagram)?

Thanks.
