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. P1–99 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?
A manometer consists of a U-shaped tube containing a liquid. One side is connected to the apparatus and the other is open to the atmosphere. The pressure p inside the apparatus is given p = pex + ρgh, where pex is the external pressure, ρ is the mass density of the liquid in the tube, g = 9.806 m s−2 is the acceleration of free fall, and h is the difference in heights of the liquid in the two sides of the tube. (The quantity ρgh is the hydrostatic pressure exerted by a column of liquid.) (i) Suppose the liquid in a manometer is mercury, the external pressure is 760 Torr, and the open side is 10.0 cm higher than the side connected to the apparatus.

The figure below shows a turbine-driven pump that provides water to a mixing chamber located dz⁢= 5 m higher than the pump, where m˙=50 kg/s. Steady-state operating data for the turbine and pump are labeled on the figure. Heat transfer from the water to its surroundings occurs at a rate of 2 kW. For the turbine, heat transfer with the surroundings and potential energy effects are negligible. Kinetic energy effects at all numbered states can be ignored. Determine:(a) the magnitude of the pump power, in kW.(b) the mass flow rate of steam, in kg/s, that flows through the turbine.
