1-99 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. Pl–99 has a spring constant of 8 kN/cm. The pressures are P, = 5000 kPa, P2 = 10,000 kPa, and P, = 1000 kPa. If the piston diameters are D, = 8 cm and D, = 3 cm, how far will the spring be deflected? Answer: 1.72 cm

1 - 2 3 The rectangle above is a control volume. Flow 1 is 2.7 slugs/sec while flow 2 is 8.4 slugs/sec. The fluid has density 1.3 slugs/ft³. Determine the volumetric flow rate of flow 3 in ft³/sec. Answer with a positive number if the flow is out of the control volume and a negative number if the flow is into the control volume. Your answer should include at least one digit after the decimal place. Hint: Use continuity

Oil SG= 0.85

mass should be kg, not N. Make your own assumption. I shall correct accordingly.
