3.5 price of oil (see Fig. 3.4). 3.6 Discuss the challenges facing CCS technologies. 3,.7 Investigate what methods are being considered for CCU. 3.8 An adiabatic compressor increases the pressure of water from 0.04 bar to 150 bar. Assuming that water is incompressible, calculate the work done per kg of water. Using the following steam table data, estimate the work done on an adiabatic turbine by i kg of superheated steam entering the turbine at a pressure of 200 bar and a tempera- ture of 600 °C and leaving the turbine at a pressure of Ibar and a temperature of 100 °C 3.9 Steam table data T (°C) p (bar) h (kJkg) 100 2676 3537 600 200Explanation / Answer
Q9.
The amount of work done= h2 -h1.
where h denotes the enthalpy of the adiabatic system.
work done= 3537- 2676 (data from the steam table)= 861kj/kg
