While reading a paper i have come across an equation in the following form;
a = b - f(c) \leq 1
What is this style of equation called and how do you solve them?
Thanks
Confused
This is NOT homework. The fan is a Crary Fan and the hose is Oregon PU used to distribute particles. I have tried a number of 'online' calculation sites but they return either conflicting results or 'infinite' values!
Dear All
I am trying to determine / estimate the expected air...
Would the true mass of the piston at the moment of impact be its mass due to its material (7 kg) plus the effective mass due to the pressure acting on the end of the piston due to the oil pressure (11 N/mm2 x 12250mm2) / 9.81 = 13736 kg giving a total mass of 13743 kg.
Pressure = 110 Bar (11...
You could consider using gear type flow dividers to divide the oil flow equally. There would be minimal oil flow across the divider which would be a problem if the loads on each cylinder was not equal. You would also need to incorporate double overcentre valves as a safety measure should a hose...
The duration of the impact is approx 0.2 seconds.
The mass of the piston and the rod is 7 kg (only part moving)
The nominal bore diameter is 125mm with 300mm stroke
It is impacting a fixed object towards the very end of its stroke. The oil flow is automatically reversed when the oil flow...
Hello Unrest
Reading your post and assuming the following values;
Pressure = 110 Bar (11 N/mm2)
Surface Area Pistion = 12250 mm2
Mass of Piston = 7 kg
G = 0.85
Would i be correct in calculating the impact force to be
(11 x 12250) + (7 x 0.85) = 134756 N...
I am trying to determine the maximum (instantaneous) impact force experienced by an object when it is struck by a hydraulic ram. I know both the pressure in the cylinder side of the ram and the level of deceleration (-g) experienced by the end of the rod on the ram when it stikes the object...
