The pool with a length of l = 50 m and a width of s = 15 m has a depth of h1 = 1.2 m at the shallowest part of the wall. The depth then gradually increases to a depth of h2 = 1.5 m in the middle of the pool. = 4.5 m walls in the deepest part of the pool. Consider the specific heat capacity of water c = 4,200 J / (kg · °C).
a) What is the volume of water in the pool?
b) How long does it take to fill the pool with two inlets if each flows A = 5 liters/s?
c) How much GJ of heat is needed to heat the pool water by ∆t = 10°C?
d) When filling the pool for the first time, we require that the water has a temperature of t = 25°C.
How much hot water and how much cold water will we need if the temperature of cold water t1 = 10°C and hot water t2 = 60°C?
