Adouble acting cylinder is hooked up in a regenerative circuit. the cracking pressure for the relief valv is 1500 psi. the piston area is 45 in3 and the rod area is 10 in3. the pump flow is 20 gpm. find the cylinder speed, load-carrying capacity, and power delivered to the load during the a)-extending stoke and b)-retracting stroke. assume the load equals the cylinder load-carrying capacity.

Which of the following ziegler nichols tuning methods the response of the controller to a step input should exhibit an s-shaped curve? a)-open loop mode b)-closed loop mode c)-both modes (open & closed) d)-none of the modes (open & closed)

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
