Question 1: The engineering team at Grainger company designed a shell-and-tube water-to-water heat exchanger that has a maximum heat transfer rate of 330,000Btu/hr. This is the maximum heat transfer a customer can expect to achieve in actual operation. For this heat exchanger, the maximum flow capacity of the shell and tube are 24 and 12gpm (gallons per minute), respectively. Max allowable temperature is 300F. Material is stainless steel. The shell is equipped with baffles, but the shell fluid only has one pass. The tubes enter and exit on the same side through a divided manifold and therefore have two passes. Conduction resistance is assumed to be negligible. The overall size of the system (i.e. the shell) is 5.8 inch ID and a 27 -inch long tube section. Both fluids are water. Assume the system is operating at maximum design conditions (i.e. T hot, in =300F;Q shell =24gpm, etc. from above) and that the cold fluid is from a building water supply at 70F. 1.1 (5 Points) The overall size of the system (i.e. the shell) is 5.8 inch ID and a 27 -inch long tube section. Assuming the tubes are 1/2 inch in diameter (ignore thickness) and that the tubes are spaced with 1/4 inch between them. Estimate the number of tubes that will fit in the shell
