Answer:
Explanation:
given data
loading rate = 8.00 m/h
filtration rate = 7.70 m/h
dimensions = 10 m × 8 m
filter cycle duration = 52 h
time = 20 min
to find out
flow rate and volume of water is used for back washing plus rinsing the filter
solution
we consider here production efficiency is 96%
so here flow rate will be
flow rate = area × rate of filtration
flow rate = 10 × 8 × 7.7
flow rate = 616 m³/h
and
we know back washing generally 3 to 5 % of total volume of water per cycle so
volume of water is = 616 × 52
volume of water is 32032 m³
and
volume of water of back washing is = 4% of 32032
volume of water of back washing is 1281.2 m³
Answer:
Increased, 5%
Explanation:
Recent studies conducted on online dating sites established that the response of female users increased by 5% when emotions are in their profiles even as for male users' response also increased by 8%. Another study also revealed that those who have never used online dating sites and/or mobile dating apps believe that people who use dating apps are desperate.

You may not work on any equipment if the TEACHER is not present in the room.
Answer:
Option D - the moisture content at turbine exit will decrease
Explanation:
In an ideal rankine system, the phenomenon of superheating occurs at a state where the vapor state of the fluid is heated above its saturation temperature and the phase of the fluid is changed from the vapor phase to the gaseous phase.
Now, a vapour phase has two different substances at room temperature, whereas a gas phase consists of just a single substance at a defined thermodynamic range, at standard room temperature.
At the turbine exit, since it's just a single substance in gaseous phase, it means it will have less moisture content.
Thus, the correct answer is;the moisture content at turbine exit will decrease
