Chapter 2: Dimensional Analysis Exercise!l 2019 1. Amirul Asyraf's team is to design a human-powered submarine for a design competition The overall length of the prototype submarine is 2.24 m, and its student designers hope that it can travel fully submerged through water at 0.560 m/s, The water is freshwater (a lake) at T-15°C. The design team builds a one-eighth scale model to test in ther university's wind tunnel. A shield surrounds the drag balance strut...

Water at 20°C is to be siphoned through a tube 1 m long and 2 mm
in diameter as shown in the figure below. For water at 20°C, take
ρ = 998 kg/m3 and μ = 0.001 kg/m⋅s.
Take π = 22/7. The kinetic energy correction factor
α is 2.0. What is the flow rate if H = 41 cm? Round the
answer to four decimal places.
