Software-as-a-Service for Microsoft Dynamics NAV What is SaaS? As more and more organizations are turning to Software-as-a-Service (SaaS) for their needs of technology‚ SaaS is becoming an increasingly prevalent software delivery model‚ which is commonly known as a more cost-effective and flexible alternative to traditional on-premises model. Software-as-a-Service or SaaS is a method of delivering software over the Internet. It is an on-demand software service through which a SaaS vendor hosts

Theory : The friction resistance to the flow of fluid through a pipe results in a loss of pressure energy for a given fluid flowing a long a given pipe‚ experiments show that for laminar flow : Hl α V And for turbulent flow : Hl α Vn Where : Hl :is the loss of pressure head . V : the mean velocity of flow . n : an index that lies

mechanical seal/gland packings‚bearing ‚etc. Pump is a device that moves fluids (liquids or gases)‚ or sometimes slurries‚ by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift‚ displacement‚ and gravity pumps. Pumps operate by some mechanism (typically reciprocating or rotary)‚ and consume energy to perform mechanical work by moving the fluid. Pumps operate via many energy sources‚ including manual operation‚ electricity

viscometer. The viscosity measured in a capillary viscometer is not obtained at a defined shear rate. Of several fixes to this problem‚ the simplest is simply to ignore it. This amounts to assuming that the fluid is Newtonian over the entire range of shear rates encountered by the fluid as it passes down the capillary. The Ubbelohde capillary viscometer The most useful kind of viscometer for determining intrinsic viscosity is the "suspended level" or Ubbelohde viscometer‚ sketched below:
