A salt solution is prepared in a graduated cylinder using 400 g NaCl and 1000 g water at 20 °C. Solubility of NaCl at 20 °C is 357 g NaCI/1000 water then some NaCl precipitates at the bottom of the cylinder. The density of the saturated solution is 1.2 g/ml. The diameter of the graduated cylinder is 5cm. What should be height of the cylinder. Determine concentration profile of NaCl in the cylinder from the bottom to the surface of the solution versus time.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
