A refrigerator uses refrigerant-134a as the working
Переглядів 612 годин тому
A refrigerator uses refrigerant-134a as the working fluid and operates on an ideal vapor-compression refrigeration cycle between 0.14 and 0.8 MPa. If the mass flow rate of the refrigerant is 0.05 kg/s, determine (a) the rate of heat removal from the refrigerated space and the power input to the compressor, (b) the rate of heat rejection to the environment, and (c) the COP of the refrigerator.

An aircraft is flying at a cruising speed 5000 m where atmospheric pressure is 54.05 kPa and the ambient air temperature is 255.7 K. ambient air is first decelerated in a diffuser before it enters the compressor. Assum both the diffuser and the compressor to be isentropic, determine (a) the stagna pressure at the compressor inlet and (b) the required compressor work per unit ma the stagnation p...

Distribution Load Problem
Переглядів 2619 годин тому
A distribution load problem typically involves analyzing how a load is spread over a certain area or length, rather than being concentrated at a single point. This is common in fields like structural engineering and mechanics. Key Concepts: Intensity: The load per unit length, area, or volume. It's often denoted as ( w ) and measured in units like N/m or lb/ft1. Equivalent Point Load: For simpl...

Helped me a lot on my review. THANKSSS!!
what is this book?
thank u so much and i think u forgot that it was a triangle and that we were supposed to divide it by cos 30. and again THANK YOU. i didnt even know where ot begin with this question.
ভাই,বুঝলে বাংলায় বুঝান,কি কইতাছেন,কিছুই বুঝি নাহ
Please try typing rather then writing
Awesome explaining Plss keep posting
