[화학공학] Measurement of Pressure Drop through Pipe Accessories 실험

Measured value taken from h8. This is the head recorded the Total Head Probe.2. 3. Mechanical Energy Balance(=engineering Bernoulli equation)alpha2 over 2 v2^2 +gz2 = alpha1 over 2 v1^2 +gz1 - int from p1 to p2 dp over rho + delta Ws -lv p : static pressure detected at a side holev : fluid velocityv^2 V over V^3 z : vertical elevation of the fluidα : delta Ws : shaft worklv V : losses for unit mass( is for viscous losses)3. 실험 방법3. 1. MaterialsWater 3. 2. Apparatus▶ The F1-10 Hydraulics Bench which allows us to measure flow by timed volume collect

실험적 결과에 의해 P’은 P1과 같으므로 P1A1 항이 사라집니다. 또한 부피유속 Q는 A2V2 로 나타낼 수 있으므로 최종적으로 P1-P2는 최종적으로 ( )로 나오게 됩니다. 이를 베르누이 방정식에 넣어 정리하면 head loss는 ( )이 됩니다.Flow through abrupt but finite enlargement (b) Flow at Infinite enlargement (Exit Loss)1번식에서 2번식으로 갈때 where A1, A2 are the cross-sectional areas of the smaller and larger parts of the pipe respectively, Q is the volumetric fllow rate and p’ is the mean pressure of the eddying

Through diligent study, however, he education himself and became a learned man. 그러나 열심히 공부하여 스스로 깨우쳤고 박식한 사람이 되었다.For a while he held a minor government post; but he soon resigned that position and spent most of his life as a teacher. 잠시 동안 그는 중요하지 않은 관리로 일했지만 곧 그만두고 선생으로 나머지 생을 살았다. Eventually, his most important teachings were gathered together into a book, the Analects, which was compiled by his disciples. 결국 그의 중요한 가르침들이 모아져 그의
