Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. T…

Textbook Question

Chapter 15, Problem 16ICA

Determine solutions to the following problems

a. Assume the matrix springData has two columns. Each row (pair of numbers) represents data about a specific spring. The first column contains a force in newtons, and the second column contains a displacement in inches that the corresponding force caused in that specific spring. With a single MATLAB command, add a third column to SpringData that contains the corresponding spring constant [N/m] for each data pair.

b. Assume two vectors containing the same number of elements have already been defined. RV is a row vector and cv is a column vector. Write a single MATLAB command that will calculate the sum of the products of the corresponding elements in RV and cv and place the result in SOP. For example, if RV= [2 3 4] and CV= [5;-1; 6] , then SOP-31. Once you have a working solution, find a second completely different solution. HINTS: (a) consider how matrix multiplication works, (b) use help or doc to learn about the sum function.

c. Assume you have a 2 × N matrix OD. The first row contains measurements of the volumes of various objects [m³]. The elements in the second row are measurements of the specific gravities of the corresponding objects. Determine the total mass in kilograms of all of the objects. In other words, perform the calculation

A turbocharged engine with a compression ratio of 8 is being designed using an air standard cycle. The ambient air is assumed to be 300K and 100 kPa. The temperature at the end of the compression in the cylinder is desired to be 1000K, assuming no combustion prior to reaching TDC. At the end of the cylinder expansion the temperature is also desired to be 1000K. If both the turbine and the compressor have mechanical efficiencies of 80%, what will be the pressure ratio of the compressor and what will be the turbine exhaust temperature?

Q6: A turbocharged engine with a compression ratio of 8 is being designed using an air standard cycle. The ambient air is assumed to be 300K and 100 kPa. The temperature at the end of the compression in the cylinder is desired to be 1000K, assuming no combustion prior to reaching TDC. At the end of the cylinder expansion the temperature is also desired to be 1000K. If both the turbine and the compressor have mechanical efficiencies of 80%, what will be the pressure ratio of the compressor and what will be the turbine exhaust temperature?

Q5: A 5.6 litre V8 engine with a compression ratio of 9.4:1 operates on an air-standard Otto cycle at 2800 RPM, with a volumetric efficiency of 90 % and a stoichiometric air-fuel ratio using gasoline. The exhaust flow undergoes a temperature drop of 44ºC as it passes through the turbine of the supercharger. Calculate (a) mass flow rate of exhaust gas and (b) power available to drive the turbocharger compressor.
