MECE2640 Assignment 1 2022

Mech. Engg. Dept. 4th year 2022-2023 Solar Energy Spring course MEC364 Dr. Mahmoud U. Jasim Review/Recap Sheet Q1- Answer with true or false and rewrite the false statements completely in correct form, otherwise no mark will be put on the false statements. 1 2 To represent a location on earth surface you need to define its altitude and longitude angles. 3 Solar zenith and solar incidence angles have the same value for horizontal surface. At sunset time the value of solar altitude angle is maximum. 4 The angle which represents the inclination of a given surface is the zenith angle 5 6 7 8 When the absolute value of sun-wall azimuth angle exceeds 90' this means that the sun rays are reaching the receiving plane. The solar irradiance and the solar irradiation have the same physical meaning. In the case of clear sky weather, the beam solar irradiation on a horizontal surface is less than the diffused irradiation. The total solar radiation received by a tilted surface is the same as that…

FINALS ASSIGNMENT IN ME 3215 COMBUSTION ENGINEERING PROBLEM 1: A Diesel engine overcome a friction of 200 HP and delivers 1000 BHP. Air consumption is 90 kg per minute. The Air/fuel ratio is 15 to 1. Find the following: 1. Indicated horsepower 2. The Mechanical efficiency 3. The Brake Specific Fuel Consumption PROBLEM 2: The brake thermal efficiency of a diesel engine is 30 percent. If the air to fuel ratio by weight is 20 and the calorific value of the fuel used is 41800 kJ/kg, what brake mean effective pressure may be expected at S.P. conditions (Standard Temperature and pressure means 15.6°C and 101.325 kPa, respectively)?

I need help with this before tomorrow’s exam if I can get all needed calculations please

Pl:1: this was all information that was given to me. If need j would need to look it up online.

Please answer the 4th question

I need parts 1, 2, and 3 answered pertaining to the print provided. NOTE: If you refuse to answers all 3 parts and insist on wasting my question, then just leave it for someone else to answer. I've never had an issue until recently one single tutor just refuses to even read the instructions of the question and just denies it for a false reasons or drags on 1 part into multiple parts for no reason.

This is an engineering problem and not a writing assignment. Please Do Not Reject. I had other engineering tutors on bartleby help me with problems similar to this one. This problem must be presented in a logical order showing the necessary steps used to arrive at an answer. Each homework problem should have the following items unless otherwise stated in the problem: a. Known: State briefly what is known about the problem. b. Schematic: Draw a schematic of the physical system or control volume. c. Assumptions: List all necessary assumptions used to complete the problem. d. Properties: Identify the source of property values not given to you in the problem. Most sources will be from a table in the textbook (i.e. Table A-4). e. Find: State what must be found. f. Analysis: Start your analysis with any necessary equations. Develop your analysis as completely as possible before inserting values and performing the calculations. Draw a box around your answers and include units and follow an…
