Problem $5(10$ points$)$: A capillary tube of radius $4$ mm is inserted in a reservoir filled with a fluid of

density $800k\frac{g}{m^3}$ that is open to atmosphere. The surface tension of the glass$/$fluid$/$air interface is $$

$=27$ dynes $\frac{?}{cm}$ and the contact angle between the meniscus tangent and the tube wall is $45.$ Find the

capillary rise or fall $($H$).$
