An unsteady flow refers to a fluid flow where the properties at a specific point in the flow field change with time. This could be due to variations in velocity, pressure, or density over time. It contrasts with steady flow, where these properties remain constant at any given point in the flow field over time.
Over time, the water erodes the river's banks and river beds changing it flow pattern
steady: A steady flow is one in which the conditions (velocity, pressure and cross-section) may differ from point to point but DO NOT change with time. unsteady: If at any point in the fluid, the conditions change with time, the flow is described as unsteady.
Silk is such an expensive fibre to produce due to the time consuming processes silk goes through in its manufacture. These processes change a fibre into something we might buy in the shops. Over 30 countries produce silk. The major ones are China, India and Japan. I hope I helped
hi peeps

Wealth is a stock variable because it represents the total value of assets owned at a specific point in time, rather than a flow variable which measures the change in value over a period of time.
over time the payment methods changed, varying from silk as a monetary form of payment to paper money
The Silk Road wasn't really 'built' like a highway. It developed over time as the need to transport silk that would be traded for goods from china to Europe.
Evolution is the process by which the characteristics of a population change over time through the mechanism of natural selection, genetic drift, gene flow, and mutation. This results in the adaptation of species to their environments and the formation of new species.
A change over time is often referred to as a gradual change.
Yes, evolution is the change in heritable characteristics of a population over successive generations. This change is driven by natural selection, genetic drift, mutation, and gene flow.
