CRIT 220 Week 1 Peter C Martinez

2. In studying for your CBEMS 125B exam, you get hungry and decide to boil some water in a pot to make instant noodles. You put your aluminum spoon, with a long handle (i.e. good to use "long fin approximation"), in the pot in anticipation of stirring the noodles into the boiling water. However, your phone rings, and you leave the spoon in the boiling water on the stove for quite a while (i.e. the system reaches steady-state conditions) before you come back to it. The boiling water is at 100°C and room temperature is 25°C. The spoon has a square handle that is 0.6 cm per side. At a handle height of 8 cm, the temperature of the long aluminum spoon is 62°C. The Royal Society for the Prevention of Accidents lists a maximum surface temperature of 58°C as a "safe" touchable temperature for metals. Is the spoon safe to pick up at a handle height of 12 cm? Justify your answer with calculations. Assume (1) No radiation effect, (2) convection heat transfer coefficient is uniform in the pot…

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)?

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…

LESSON: AUTODESK AUTOCAD Choose from the choices:

Task 1 You are employed as a mechanical engineer within an unnamed research center, specializing in the development of innovative air conditioning systems. Your division is tasked with providing computer-based modeling and design solutions using computational fluid dynamics through ANSYS software. Your primary responsibilities involve the analysis of horizontal channel dynamics to meet specific criteria. Under the guidance of your immediate supervisor, you have been assigned unique responsibilities within an ongoing project. As a member of the research team, your role includes constructing an appropriate model and executing a sequence of simulation iterations to explore and enhance channel performance. Figure 1 provides a visualization of the horizontal channel under consideration. Consider 2D, incompressible, steady flow in a horizontal channel at a Reynolds number of 150. The schematic below illustrates the channel flow, not drawn to scale. For simplicity, neglect gravity. The…

Problem 1: You are working in a consulting company that does a lot of hand calculations for designs in Aerospace Industry for mechanical, thermal, and fluidic systems. You took the Virtual engineering course, and you want to convince your boss and the team you work to move to modelling and simulation in computers using a certain software (Ansys, Abaqus, etc). Discuss the benefits and pitfalls of computer based models used within an industrial environment to solve problems in engineering.

Help!!! Answer all parts correctly!! Please

as per your policy, customer service from bartley stated since you took a incomplete question and answered it instead of questions that actually need answering.    you owe me my questions and not to only solve one question, kindly solve all 3. And when i end up switching to CHEG not only will i be posting this on my vlog and social media i will also be contacting BBB and i will make sure to find out whos the special kid behind answering and trolling me ((:   kindly answer all 3 , thanks

mechanical engineering (autonomous underwater vehicle) please i have project I need detailed project constraints

I want to answer all the questions by handwriting.

Hello I need an deep explanation of an engineering topic a deep dive into it. The more information the better. A)What is EUV? B)How is it important?
