Sistem pencernaan terdiri dari mulut, lambung, usus halus, usus besar, hati, dan pankreas. Organ-organ tersebut bekerja sama untuk mencerna, menyerap, dan membuang sisa makanan melalui proses yang terkoordinasi oleh sistem saraf dan hormonal.
This chapter introduces miniaturized devices that have become important for industrial applications in fields like chemical engineering, electronics cooling, automotive, aerospace, and biomedical. Transport processes in these devices are laminar due to small scales, resulting in poor mixing and heat/mass transfer. Additional mechanisms are needed to enhance transfer rates, like Dean vortices in tortuous channels. Multiphase flow also enhances mixing and rates. While single-phase flow can be predicted by macroscale correlations, multiphase flow in microchannels is not well understood. Taylor and annular flows, which occur over wide ranges of conditions, are important but heat transfer in Taylor flow is poorly understood and annular flow in microchannels is almost unstud
A wind farm is a group of wind turbines located together that are used to produce energy. Wind farms can consist of hundreds of turbines covering hundreds of square miles, though land between turbines can still be used for agriculture. For economic wind power generation, windspeeds of 16 km/h or higher are generally required. A 2010 study showed that the immediate area around wind farms is cooler during the day and slightly warmer at night than surrounding areas, due to turbulence created by the spinning blades.
