A stiff, 10-cm-long tube with an inner diameter of 3.5 mm is attached to a small hole in the side of a tall beaker. The tube sticks out horizontally. The beaker is filled with 20∘C water to a level 50 cmabove the hole, and it is continually topped off to it maintain that level. What is the volume flow rate through the tube? The viscosity of water is 1.0×10−3Pa⋅s.

[10] Design Problem As shown in the figure below, a double-pipe parallel-flow heat exchanger is used to heat cold fluid which is water (Cp = 4180 J/(kg.K), p = 1000 kg/m) from 20°C to 80°C at a rate of 0.15 kg/s. The heating is to be accomplished by hot fluid, which is geothermal water (Cp = 4310 J/(kg.K), p = 1050 kg/m²) available at 130°C at a mass flow rate of 0.25 kg/s. The inner tube has an inner diameter...
