Symptoms of a Faulty Cylinder Head Temperature SensorPro Car Mechanics
The cylinder head temperature sensor is an electronic device which helps to measure the temperature of the engine cylinder head. It plays a major role in determining the performance and efficiency of the engine. And when this sensor starts to fail, the car shows long cranking time, illuminated warning light, and low performance. In order to know more about the symptoms of a faulty cylinder head temperature sensor, see the following slides.

This so called PPT for propulsion study for Shenyang Aerospace University. This PPT right protected by Dr. divinder K. Yadav. Its using in SAU by Lale. For all students of Aeronautical Engineering must memorize each & every words from this PPT. If you miss a single words you must fail in the Exam. Remember there is no chance to be creative or use sense you just need to use the power of memorizing.
This was one of the very first CBT modules I developed. This presentation was imported into Captivate, where additional features such as mouse-over definitions were added.
Heat is a form of energy. According to the principle of thermodynamics whenever a physical or chemical transformation occurs heat flow into or leaves the system.
A number of sources of heat are used for industrial scale operations steam and electric power is the chief sources to transfer heat. It is essential to cover steam without any loses to the apparatus in which it is used. The study of heat transfer processes helps in be signing the plant efficiently and economically
The ninth lecture in the module Particle Technology, delivered to second year students who have already studied basic fluid mechanics. The different mechanisms for the removal of dust from gases are covered and the design equations used for control, modelling and understanding of the equipment are presented and derived. Examples of industrial equipment for gas cleaning are included.
This presentation was prepared by Mechanical Engineering students during their Internal Combustion Course. Students belong to a very prestigious Engineering institute of Pakistan "University of Engineering and Technology Lahore"

1. : 11- تطبيقات اللزوجة
أول : السرعة القصوى للسيارة :
بسبب خاصية اللزوجة للهواء تتناسب قوة مقاومته لحركة السيارة طرديا مع سرعتها . وبعد
حدود معينة)٠٢١ كم / س( تتناسب مقاومة الهواء طرديا مع مربع سرعة السيارة مما يسبب زيادة
استهلك الوقود .
ثانيا : قياس سرعة ترسب الدم :
تعرف بعض المراض من خلل قياس سرعة ترسب كريات الدم الحمراء خلل البلزما .
ثالثا : استخدام الزيوت في التشحيم :
من فوائد تشحيم اللت :
1-تقليل الحرارة الناتجة عن الحتكاك .
2-حماية أجزاء اللت من التآكل .
قانون ستوكس :
نصه : قوة مقاومة)قوة اللزوجه( المائع لكرة تسقط سقوطا حرا فيه تناسبا طرديا مع لزوجة هذا المائع
وقطر الكرة وسرعتها الحدية .
ول يستخدم هذا القانون إل في حدود معينة للسرعة .
السرعة الحدية : ثبوت السرعة للجسام الساقة في المائع .
فعند السرعة الحدية نجد أن قوة الممانعة ) قوة اللزوجة ( تعطى بالعلقة التالية :
ق اللزوجة = × ٦ πمل × نق × عالحدية
وتكون قوة الممانعة دائما مؤثرة باتجاه معاكس لتجاه حركة الجسم داخل المائع .
فعندما يكون الجسم متحرك نحو السفل :
قالطفو قالطفو
قاللزوجة + .......= وزن الجسم قاللزوجة + قالطفو = وزن الجسم
قاللزوجة أما عندما يتحرك الجسم نحو العلى :
قالطفو = ....... + وزن الجسم قالطفو = قاللزوجة + وزن الجسم
ق
اللزوجة
الوزن الوزن
الحركة إلى أسفل الحركة إلى أعلى
