A single-effect evaporator generates a distillate product at a flow rate of 2 kg/s. The system operating temperatures are as follows: • The boiling temperature, Tb is 90 ºC. • The feed temperature, Tf, is 85 ºC. • The steam temperature, Ts, is 100 ºC. • Boiling Point Elevation is neglected. • The Temperature of cooling Water, Tcw, is 25 ºC.
Determine the heat transfer areas in the evaporator and the condenser, the thermal performance ratio, the flow rates of feed seawater and reject brine, and the flow rate of cooling seawater.
Assume that the specific heat of seawater is constant and equal to 4.2 kJ/kg.ºC, and assume the over all heat transfer coefficeint for evapporater and condenser is 2 kW/m2 .ºC ,and assume the salinity of the feed is 42,000 ppm and rejected brine salinity is 84,000 ppm.

Question 3: Explain pressure. ( it is advised to look at the supplied materials and explain from them)
Supplied Materials:
-For static fluids, consider the force balance. Fluid
statics.
is there. In the case of liquids, the change in pressure due to
height is large, and it must be handled. Also, even when the
container is in a relatively stationary state, for example, when
the container is operating at high speed, it is possible to think
of the motion of the fluid in the target system fixed to the
container as if it were the stationary fluid.
3.1 Pressure p.22~
p expressed as p=P/A is called Pressure and P is called total
pressure. When the pressure is not uniform, the pressure at one
point is p=lim ΔA→0 (ΔP/ΔA)=dP/dA
Is displayed.
3.1.1 Unit of pressure p.22~
・In SI unit, the unit of pressure is often expressed as Pascal (Pa)
or Bar (bar) or Water column meter (mH2O, mAq). Refer to Table 3.1
on page 23 of the textbook for pressure unit conversion. Of these,
remember the following three in particular. 1Pa=1N/m2
1atm=101325Pa
1mHg=1/0.76atm
Pa is the basic unit of pressure, atm is 1 atm, and 1 mHg is used
for conversion when measuring mercury column.
3.1.2 Absolute pressure and gauge pressure p.23~
・There are the following two methods to express the pressure. Be
careful not to be confused.
(See Figure 3.1 in textbook p.23.) Absolute pressure: A method
based on perfect vacuum. Gauge pressure: A method based on
atmospheric pressure. (Gauge pressure) = (Absolute
pressure)-(Atmospheric pressure) In other words, the gauge pressure
indicates whether or not there is a pressure difference from
atmospheric pressure. Therefore, the pressure measuring instrument
usually shows gauge pressure, so it is necessary to consider the
atmospheric pressure.
3.1.3 Properties of pressure p.23~
・Pressure has the following three properties. (1) The pressure of
the fluid always acts vertically on the wall surface in contact
with the fluid. (2) The pressure at one point in the stationary
fluid is the same in both directions. (3) The pressure applied to
the fluid in the closed container is transmitted to all parts with
the same strength. Pascal principle: F2/A2 = F1/A1
∴ F2 = F1 × (A2/A1)
End of supplied materials. Thank you so much, and I hope you are able to deliver this. The explaination shouldnt be short but not too long either is thats not a bother
