2.1 Discussion Conduction
J-R:
Complete the following:
Research a device that uses a conductive heat exchange to perform its
task. State the actual heat transfer goal of the device (i.e., for the oven, its goal is to keep a constant temperature).
Hello Class,
A system of heat exchange I am familiar with is the cooling systems on
board a ship (Vessel). There are two cooling systems used as heat exchanges. The first one is a sea water system used for the machinery systems as a cooling or heat exchanger. The second one is a Fresh water/Central Cooling which is used in a closed circuit to remove heat from the engine’s rooms equipment. Somewhat like a car engine cooling system. The first sea water system is used to cool or remove heat from the freshwater closed circuit.
I would think that this would be a Transient Heat transfer and not a Steady-State heat Transfer. You would have to take all components into consideration when doing an analysis of the system. The
dimensions would be in the heat exchanger and pump and tubing/piping would need to be looked at dimensionally.
Describe the task and determine if steady-state or transient heat transfer analysis is appropriate. (Since an oven is designed to keep a steady temperature, steady-state heat transfer analysis would be appropriate.)
Determine the number of dimensions that would have to be considered
for this analysis. (In the oven's case, one dimension could be the correct design tool.)

You are an engineer in a company that manufactures and designs several mechanical devices, and your manager asked you to help your customers. In this time, you have two customers, one of them wants to ask about internal combustion engines while the other requires a heat exchanger with particular specifications. Follow the parts in the following tasks to do your job and support your customers.Task 1:Your first customer asked for an internal combustion engine to use it in a designed car. Your role is to describe the operation sequence of different types of available engines, explain their mechanical efficiency, and deliver a detailed technical report which includes the following steps:STEP 1Describe with the aid of diagrams the operational sequence of four stroke spark ignition and four stroke compression ignition engines.STEP 2Explain and compare the mechanical efficiency of two and four-stroke engines.STEP 3Review the efficiency of ideal heat engines operating on the Otto and Diesel…

Part 1: Do the Analysis of the Ocean Thermal Gradient Power Plant shown
below. Your Analysis will be easier to do in EES but it is up to you. Your
EES program must be well documented and documentation in your code
should reference system sketches. (The cycle and individual components)
These sketches are done on attached engineering or typing paper, unless
you are able to draw them in EES. You must validate your results with hand
calculations on engineering paper that invoke the 1 and 2 Law from the
perspective of the entire cycle, not the individual components. Of course,
a system sketch is required.

Cycle operates with a peak boiler temperature of 70 °F and a condenser
temperature of 40 °F. The warm surface water of the ocean is supplying
the thermal energy to the boiler. Assume a high source temperature of 80
°F. The cooler water deeper in the ocean is the sink for heat rejection at
the condenser. Assume a…

Problem 1: Gnome Ride - This from a Previous Exam
I.
A Gnome of given mass M goes on the Gnome Ride as follows: He stands on a horizontal
platform that is connected to a large piston so that the platform is driven vertically with a position
as a function of time according to the following equation:
y(t) = C cos(wt)
Here w is a constant given angular frequency, C is a given constant (with appropriate physical
units) and y represents the vertical position, positive upward as indicated.
Part (a) - What is the velocity of the Gnome at time t = 0? Explain your work. Present your
answer in terms of the given parameters
Part (b) – What is the net force on the Gnome at time t = 0? Explain your work. Present your
answer in terms of the given parameters
Part (c) – What is the Normal Force on the Gnome at time t = 0? Explain your work. Present
your answer in terms of the given parameters

3. Properties of Pump Systems - II
Learning Objectives: This problem builds on the pump examples we have been doing, but is meant to help
you learn to do proofs in a step by step fashion. Can you generalize intuition from a simple example?
We consider a system of reservoirs connected to each other through pumps. An example system is shown
below in Figure 1, represented as a graph. Each node in the graph is marked with a letter and represents a
reservoir. Each edge in the graph represents a pump which moves a fraction of the water from one reservoir
to the next at every time step. The fraction of water moved is written on top of the edge.
Figure 1: Pump system
We want to prove the following theorem. We will do this step by step.
Theorem: Consider a system consisting of k reservoirs such that the entries of each column in the system's
state transition matrix sum to one. If s is the total amount of water in the system at timestep n, then total
amount of water at timestep n +1 will also be…
