This $30^($@$)$ vertical bend in the figure below, for the $20-$inch diameter pipe carries water at a rate of $10$ cfs$.$ If the pressure at the lower end of the bend is $65$ psi $,$ where the elevation is $100$ feet, and the pressure at the upper end is $24$ psi where the elevation is $103$ feet, what will be the vertical component of force $($in pounds$)$ that must be exerted by the anchor on the bend to hold it in the position shown? The bend itself weighs $400$ pounds and the length; L is $8$ feet.
