Question: Water is flowing in the shell side of a heat exchanger. The water may be modeled as flowing parallel to the tubes. The water enters at 80°F and leaves at 150°F. The inside diameter of the shell is 12 in., the outside tube diameter is 1.125 in., and there are 50 tubes in the heat exchanger. The water flow rate through the heat exchanger is 800 gal/min.
(a) Calculate the equivalent diameter for the flow on the shell side of the heat exchanger.
(b) Calculate the average shell-side heat transfer coefficient.
A horizontal 2.00-m long, 5.00-kg uniform beam that lies along the east-west direction is acted on by two forces. At the east end of the beam, What is the angular acceleration of the beam
In practice, a minimum of 25mm clear spacing between the bars is recommended to ensure free flow ofconcrete around each bar (note concrete contains usually 20mm max size aggregatesand additional 5mm for free flow). If the beam is required to be reinf..
