A cylinder is required to life a load of 120 kN in a system. Fluid pressure available is 15 Mpa. What cylinder size is required? A pump supplies oil at 0.0016 m3/s to a 40 mm diameter double acting hydraulic cylinder. If the load is 5000 N (extending and retracting) and the rod diameter is 20 mm, find the; (i) hydraulic pressure during the extending stroke; (ii) piston velocity during the extending stroke; (iii) cylinder kW power during the extending...

I need answer of this question please
A pipe bends through 90 from its initial direction. The pipe reduces in diameter such that the velocity at outlet is 1.5 times the velocity at inlet. The pipe diameter is 200 mm and static pressure is (100 10X) kPa at inlet. The volume flow rate is 0.2 m'/s. calculate the following: 1) Velocity at outlet 2) Pressure at outlet 3) The horizontal and vertical forces on the bend 4) The total resultant...

Question 2 (30 marks) (a) A fluid flowing into a nozzle with specific enthalpy of 2980 kJ/kg and the velocity is 80 m/s. At the exit of the nozzle, the specific enthalpy of the fluid drops to 2670 kJ/kg. The nozzle orientation is horizontal and the heat loss is negligible. Given that the nozzle inlet area is 0.25 m2 and the specific volume of the fluid is 0.2 m2/kg, calculate the velocity of the fluid at exit, the mass flow...

Consider the pneumatic cylinder as shown in Figure 1 which is an illustration from the Starcyl space-saver range, as can be found in their Star2.pdf catalogue, www.starcyl.com. Some pneumatic cylinders can have a push/pull rod (item I in Figure 1) protruding from either head (item A in Figure 1), but this cylinder clearly has only one, making it a “single rod end” type of cylinder. This cylinder is however “double acting”, which means it can be pressurised on either side...
