2. In comparison to the theoretical plots, the countercurrent and the cocurrent seem to follow the same
pattern. But for the countercurrent plot the cold water seems to dip lower as the distance increases, but
in theory the cold water decrease
Calculation
Used the data from case one in countercurrent operation. All calculations were done with the specific
heat as 4.178.
Using Equation 1 to get the heat emitted

Objective
The objective for this lab is the analysis of a heat exchanger. The system will be on focused on a plate and
shell heat exchanger. We will be changing variable such as temperature and flow rates to observe the
changes within the heat exchanger.

Objective- This objective of this lab is to determine an unknown mixtures composition using viscosity of
certain liquids.
Background
The method for finding the viscosity is through the force balance equation (figure 1). Since h>d, the
pressure gradient is

3. The calculated viscosity is much different from the online. The calculated viscosity was in most cases
greater than the viscosity obtained online.

Log mean temperature difference: It is difficult to define the temperature difference necessary to
determine the total heat transfer. There are many different temperatures involved in the transfer
of heat through this system
Discussion2. For countercurrent flow, the hot and cold liquid both have increased temperature drop rates increase
as distance is increased. The theoretical graph shows this, but the temperature drop rate actually
decreases as distance increases.
