To find the slope, use the equation: m = y2 - y1 / x2 - x1
Hope this helps!
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.
Nope.... Weight of object changes due to change in gravity but mass remains constant...
Answer: reaction force = -558N
Explanation:
w = f = 558N
since action force and reaction force are equal in magnitude and opposite in direction,
reaction force = -(f)
reaction force = -558N
if that helps.
