What is L in Nusselt number? It is defined as. where α is convective heat transfer coefficient, L is representative dimension (e.g., diameter for pipes), and λ is the thermal conductivity of the fluid. Nusselt number is a measure of the ratio between heat transfer by convection (α) and heat transfer by conduction alone (λ/L). […]
Do you need to lift heavy for hypertrophy?
Do you need to lift heavy for hypertrophy? The traditional method for building muscle mass, for both men and women alike, is to lift heavier weights and increase the amount of weight over time. If they aren’t under tension long enough, they won’t be able to promote hypertrophy (muscle growth) as effectively. What are 5 […]

Is needed to determine the position of an object? the rate of change in velocity. To identify an objects position, you must compare its location with that of another object or place. What happens when two objects? Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two […]
What factor affects the strength of water current?
What factor affects the strength of water current? Waters density is affected by its temperature and salinity, or saltiness. The colder and saltier the water is, the denser and heavier it is. Cold, dense water tends to sink and flow under warmer, lighter water, creating a current. Where is the fastest flow in a river? […]

Is carbon a tetrahedral?
Is carbon a tetrahedral? Tetrahedral carbon: A carbon atom with four attachments, and bond angles of approximately 109.5o. The overall shape is that of a tetrahedron (i.e., a pyramid with all faces being equilateral triangles, or nearly so). The carbon atoms uses sp3 orbitals to achieve this geometry. All bond angles approximately 109.5o. Is carbon […]
