Question
Chapter 48, Problem 1RQ
To determine
The correct option for the pressure swtich.
Expert Solution & Answer
Explanation of Solution
Refer to the circuit in Figure 48-6 in the text book. The pressure swtich found the application where it is necessary to sense the pressure of the pneumatic or hydraulics system.
The pressure switch in the figure is normally closed and is held open as the circuit must be completed before the pressure is released.
Thus, the correct option is d. The normally closed held open.

Design and assemble on the fluidsim (or a draft) the Hydraulic Drive Circuit, with the following characteristics:
(a) Sequential operation, pressure, for the advance and return of the cylinders (according to the proper operation for the device) controlled by a directional 4x3 way, closed center;
(b) Speed control for the cylinders, according to the load signal;
(c) Pressure counterbalance for cylinder A, in order to compensate for the weight of the assembly.
This is an old exam practice question. The answer is Pmax = 218.8 kN normal stress governs but why?
Moist air initially at T₁ = 140°C, p₁ = 4 bar, and p₁ = 50% is contained in a 2.0-m³ closed, rigid tank. The tank contents are cooled to T₂
35°C.
Step 1
Determine the temperature at which condensation begins, in °C.
