A portion of the WEC performance (kW) of the 750-kW Pelamis system is shown in Figure P8.4 Suppose this machine is located in the vicinity of a buoy having the wave scatter diagram shown in Table 8.5. A) What is the energy available in the waves at that location that have a 2-m significant wave height and an 8-s peak wave period?
B) Assuming power take-off losses of 25%, how much energy (kWh/yr) would be delivered by the Pelamis machine from those same 2-m, 8-s waves?
C) This Pelamis (sea snake) is 180-m long. What fraction of the energy in the waves that impact this machine is actually delivered?

A portion of an ammonia (NH) refrigeration cycle is shown in the figure below. Two streams enter a mixing chamber with one exit stream. One stream with mass flow rate my firsts enters a heat exchanger at Ti= 30 °C (state 1), is cooled to 15 °C (state 2) and then enters the mixer. The rate of heat transfer from the water side of the heat exchanger, Q7, is 100 kJ/s. The second stream with mass flow rate na -2...
