Answer:
(a) The consistency as a function of time is C=0.15*t.
(b) The tank will become clogged in 24 minutes.
Explanation:
The rate of accumulation of the pulp stock can be defined as
In this case, Co is 0, because the exit flow is only water and 0% fiber.
Rearranging adn integrating
At t=0, C=0,
(b) The time at when the concentration reaches 6% is 0.4 hours or 24 minutes.
Answer:
= 9,593.1 Joules
Explanation:
Heat absorbed by water is equivalent to heat released by copper.
Heat absorbed is given by;
Q = mcΔT
where m is the mass, c is the specific capacity and ΔT is the change in temperature.
Therefore;
Since dnsity of water is 1 g/mL, and specific heat capacity is 4.18 J/g°C while the change in temperature is (75-24) = 51°C.
Heat absorbed by water = 45 g × 4.18 J/g°C × 51
= 9,593.1 Joules
Therefore, the heat released by copper is 9,593.1 Joules
Answer:
in physics we never work with minutes only seconds.
