Answer:
- the process should operate each day for 7.9286 hours
- the amount of brine that must be fed to the evaporator is 94.594 kg/hr
Explanation:
Given that;
concentration of brine = 26%
so water concentration will be 100% - 26% = 74%
for evaporation of 70kg water per hour, residual is pure salt( 0% moisture)
so mass flow rate of brine = 70/(74%) = 70/0.74 = 94.5945 kg/hr
Amount of pure dry salt produced(0%) = 94.5945 - 70 = 24.5945 kg/hr
Now for production of 195kg of pure dry salt, number of hours required will be
T = 195 / 24.5945 = 7.9286 hrs
Therefore the process should operate each day for 7.9286 hours.
Total brine solution required ( 26% salt conc.) = 195/0.26 = 750 kg
Feed rate of brine solution ( 26% salt conc.) = 750 / 7.9286 = 94.594 kg/hr
Therefore the amount of brine that must be fed to the evaporator is 94.594 kg/hr

Answer:
Mechanical energy is conserved in the presence of following forces:
a) electrostatic force
b) magnetic force
c) gravitational force
Explanation:
Give data:
potential difference ,
we Know change in potential energy is given as
therefore, change in potential energy U is
let speed of particle is v
from energy conservation theorem
loss of electrical PE = KE gained
solving for v
Mechanical energy is conserved for following forces:
a) electrostatic force
b) magnetic force
c) gravitational force
