A pump is tested for cavitation using the test rig. Water at 20°C is pumped and the inlet pipe diameter is 100 mm. The valve in the inlet line is gradually closed until the pump starts to cavitate. At this point the flow rate is 24 L/s and the vacuum reads 62 kPa of vacuum. Evaluate for the given flow rate, b. i. the NPSHA (Net Positive Suction Head Available) ii. the NPSHR (Net Positive Suction Head Required) to be specified if a 5% safety margin is allowed.

F-m question. Provide right answer
In your new position at the fluid mechanics laboratory, you are required to do a to d branching. a) You perform a set of testing to measure the viscosities for various fluids: Engine oil, aluminum, zinc, water and 1:10 ratio of (corn starch: water). Pick and justify one type of viscometer for each type of fluid then, justify why a specific viscometer will not work for a type of fluid as follow: I would use I would not use Engine oil Aluminum Zinc Water Cornstarch solution Justify your answers in one statement each for each of the boxes in orange (total of 10 sentence b) For water you obtained the following data: Temperature [K] 300 310 318 340 Viscosity [cP] 0.8509 0.6913 0.5958 0.42 What is the viscosity of water at 290 K, 312 K and 350 K?

Two oils are tested to establish their viscosity index. Oil "A" and Oil "B" have their viscosity measured at temperatures of 40C and 100C. Oil "A" has a viscosity of 80Cst at 40C and 8Cst at 100C. Oil "B" has a viscosity of 90Cst at 40C and 15Cst at 100C. Which oil has the higher viscosity index?
