Does thermal conductivity depend on temperature? The effect of temperature on thermal conductivity is different for metals and nonmetals. In metals, heat conductivity is primarily due to free electrons. In alloys the change in electrical conductivity is usually smaller and thus thermal conductivity increases with temperature, often proportionally to temperature. What is the temperature dependence […]
How do you solve a problem?
How do you solve a problem? Here are seven-steps for an effective problem-solving process. Identify the issues. Be clear about what the problem is. Understand everyone’s interests. List the possible solutions (options) Evaluate the options. Select an option or options. Document the agreement(s). Agree on contingencies, monitoring, and evaluation. How do you solve a problem […]

What is the velocity profile for laminar flow?
What is the velocity profile for laminar flow? The laminar velocity profile of the fluid flow governed by the pressure gradient is parabolic. where R is the tube radius, v(max) is the maximal velocity or the centerline velocity of the velocity profile. It is assumed that there is only one velocity component in the tube […]
How the specific gravity of fine aggregates affects the design of concrete mix?
How the specific gravity of fine aggregates affects the design of concrete mix? Specific Gravity Bulk specific gravity, which is measure of volume occupied in concrete including solid aggregate particles and voids between them, is required for proportioning of concrete mixture. In contrary, a lower specific gravity of sand will result in lower density of […]
What is wet steam dry steam and superheated steam?
What is wet steam dry steam and superheated steam? Pressure-Temperature Relationship of Water & Steam Saturated (dry) steam results when water is heated to the boiling point (sensible heating) and then vaporized with additional heat (latent heating). If this steam is then further heated above the saturation point, it becomes superheated steam (sensible heating). What […]

Can exchange mass and energy with the surroundings?
Can exchange mass and energy with the surroundings? An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. An isolated system is one that cannot exchange either matter or energy with its surroundings. What […]
