3. Find the size of the struts required to restrain the fitting. The fitting is part of a refinery that processes gasoline (S=0.68). The struts are made of a material having an allowable stress of 2.5 Ksi. The weight of the fitting is 3,000 lbs.Though the fitting is curved, the size of the fitting transitions uniformly over its 12 foot length. Assume no losses through the fitting. The discharge through the fitting is 5,000 Gpm.
