Is there head loss in laminar flow? For laminar flow, the head loss is proportional to velocity rather than velocity squared, thus the friction factor is inversely proportional to velocity. The Reynolds number must be based on the hydraulic diameter. Blevins (Applied Fluid Dynamics Handbook, table 6-2, pp. 43-48) gives values of k for various shapes. What is the expression for head loss due to friction? In fluid dynamics, the Darcy–Weisbach equation is an empirical equation, which relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid...

What is a major difference between capitalism and communism? In a capitalist economy, production is determined by free market forces such as supply and demand. In a communist economy, the government determines which goods and services get produced and how much is available at any given time. How are communism and capitalism similar and different? Capitalism uses democracy and “free markets” to efficiently allocate capital to its most efficient use with little regard to economic equality. Communism focuses instead on massive state run “planned” economies allocating resources equally with little regard to personal ambition or incentive. What do sociologists believe...

What small animals burrow? Burrowing animals are the prime suspects when a homeowner discovers tunnels and holes in the yard. Many kinds of small animals, such as moles, voles, chipmunks and rats, make holes in the ground. Some, such as moles, create complex tunnel systems, while others, such as rats, dig burrows in which to hide. What kind of animal lives in a burrow? Some mammals that make burrows are moles, gophers, groundhogs, rabbits, meerkats, and kangaroo mice. The biggest mammal that makes a burrow is the polar bear. What is burrowing in my garden UK? Bank voles, wood mice...

Qual a pecuária extensiva? A pecuária extensiva consiste na criação a pasto, geralmente sem grandes investimentos e com a ocupação de grandes áreas, podendo ser realizada tanto em grandes latifúndios quanto em pequenas áreas familiares. É o cultivo do gado solto, com certa liberdade, considerado ideal para o chamado “gado de corte”. Como funciona a pecuária semiextensiva? A pecuária semiextensiva não tem um padrão definido de atuação, ao que, na prática, consiste na mescla do sistema extensivo com alguns investimentos da pecuária intensiva. Ou seja, o gado é criado solto, em grandes extensões de terra, mas recebe tratamento especial, principalmente...
