A heat pump that operates on the ideal vapor-compression cycle with refrigerant-134a is used to heat water from 15 to 45°C at a rate of 0.12 kg/s. The condenser and evaporator pressures are 1.4 and 0.32 MPa, respectively. Determine the power input to the heat pump.
Determine the coefficient of thermal expansion (in m/m.K) for the material over the temperature ranges - Determine i. the phases present
Use the same conditions as (a), except a rainstorm covers the TCE with 1 cm of water. Assume TCE dissolves into water and quickly reaches equilibrium with the water.
