Answer:
(a) The rate of heat transfer is <em>238.26 kW.</em>
(b) Rate of entropy generation is <em>0.063 kW/K.</em>
Explanation:
(a) Taking the heat gained by the cold water into consideration,
<em></em>
<em>Q = (0.95 kg/s)(4.18 kJ/kg.⁰C)(70-10) = 238.26 kW.</em>
(b) Entropy generation = entropy in cold water + entropy in hot water
But
∴ = (0.95)(4.18)(ln(343/283)) + (1.6)(4.19)(ln(1- (238.26/((1.6)(4.19)(358))))
= 0.7636 + (- 0.7009) = 0.0627 kW/K.
True. An electrolytic cell has three component parts: an electrolyte and two electrodes (a cathode and an anode)
Force of gravity on an object is the weight of the object and is given by mass times accerelation due to gravity. The accerelation due to gravity is the accerelation of an object in free fall and is given by 9.8m/s^2. Given that the force of gravity acting on a child's mass on earth is 490 newtns, i.e. F = mg which means that 490 newtons = 9.8 times mass. Therefore, mass of the child is 490 / 9.8 = 50 kg.
