Water enters a nominal 3 inch schedule 40 pipe at 1.5 m/s and experiences a 90 degree curve down, followed by a 90 degree turn to level out the pipe again. the pipe is composed of 3 segments each 4 m long. if the water has a density of 997 kg/m3 and the pressure difference between the two ends of the pipe is 15 kpa, what size of thrust blocks will be required and at what angle will they need to act?

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

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
