Heat transfer and fluid flow - Coursework ExampleThe paper allow for develop with the exercise with Heat Transfer and Fluid Flow Subjects for all Seasons. During the hot Summer one year, a loving and indulgent father set up a swimming pool in the tend for his children. The swimming pool is 3 m in diameter and filled with water to a learning of 0.8 m, using a pump that operates at a delivery pressure of 2 bar gauge. The indicator rating of the pump is 500 W. Assuming that the pump motor operates with 60% efficiency, estimate how long it will take to fill the pool. To get the time we employ the following equation, dt = (D2/d2) (dh/2gh)Where t=timeD=diameter of the poold= diameter of the hosepipeh=heightg= gravitational accelerationintegration this equation we get,t= (h/0.5g) (D2/d2)t= (0.8/0.5*9.8) (32/0.32)To warm the water in the pool, the father (who may or may not be a chemical engineer) laid black plastic over the arise of the pool to catch the solar radiation. The solar flux on a hot sunny mean solar day in Northern England is typically 700 W m2. Assuming that the black plastic acts as a black body and absorbs all of the solar radiation that falls on it, delivering this energy to the water, and ignoring radiation blanket to the sky or heat transfer with the ambient air, estimate the increase in temperature of the water in the pool after 12 hours of unbroken sunshine.
