For an inlet valve, the mass flow rate through the valve is 0.44 kg/s. The flow coefficient is 0.62 and the cylinder pressure is 105 kPa. Assume intake system pressure and temperature are 180 kPa and 527 K, the specific heat ratio is 1.3 and R =287 J / kg.K.

4. A heat exchanger creates energy loss in the fluid system shown below. Water at 50°C flows vertically upward
at a constant volume flow rate of 6 x 10-3 m³/s. A mercury manometer is used to measure pressure difference
between points 1 and 2. Evaluate the total energy loss (in a unit of m) between points 1 and 2. Using the
velocity in the inlet tube, evaluate the minor loss coefficient K corresponding to the heat exchanger. The
pipe geometry and mercury manometer setup are indicated in the figure. In the figure, OD indicates the
outer diameter of pipe. The specific weights of water and mercury are water = Pwater9 = 9.81 kN/m³ and
133.7 kN/m³, respectively. Ignore the volume flow rate of water into or out of the mercury manometer, but
one cannot ignore the contribution of water to the manometer measurement.
