The force generated by a spring is given by F = kx, where k is the spring constant and x is the deflection of the spring. The spring of Fig. 1–99 has a spring constant of 8 kN/cm. The pressures are P1 = 5000 kPa, P2 = 10,000 kPa, and P3 = 1000 kPa. If the piston diameters are D1 = 8 cm and D2 = 3 cm, how far will the spring be deflected? Answer: 1.72 cm

- A container is filled with oil and water. The weight of the same container when half filled with a liquid (s=1.95) alone is 90kN. If the volume of water is twice that the volume of oil, find the specific gravity of the oil so that the weight of the container when fully filled with oil-water combination is the same when half filled with the aforementioned liguid.arrow_forward1-107 A pressure cooker cooks a lot faster than an ordinary pan by maintaining a higher pressure and temperature inside. The lid of a pressure cooker is well sealed, and steam can escape only through an opening in the middle of the lid. A separate metal piece, the petcock, sits on top of this open- ing and prevents steam from escaping until the pressure force overcomes the weight of the petcock. The periodic escape of the steam in this manner prevents any potentially danger- ous pressure buildup and keeps the pressure inside at a con- stant value. Determine the mass of the petcock of a pressure cooker whose operation pressure is 100 kPa gage and has an opening cross-sectional area of 4 mm2. Assume an atmo- spheric pressure of 101 kPa, and draw the free-body diagram of the petcock. Answer: 40.8 g i e Patm = 101 kPa Petcock -A = 4 mm2 1.

- As shown in the figure below, a piston-cylinder assembly contains 1 kg of water at T1=200° C and P1 = 1.5 bar holding the piston against the stops. The atmospheric pressure is 1 bar, and you can assume the piston's weight is negligible. The water is slowly cooled until the piston just begins to move downward in the cylinder. What is the pressure (P2), temperature (T2), and volume (V2) of water at this point? (°C), V2 = P2 = (m³) The cooling continues until water has entirely turned into saturated liquid.
