Please solve using the methodology (Given, find, schematic diagram, solution and discussion)! Please! A deaerator heater supplies 150 L/min of deaerated feedwater into a booster pump at 115°C pumping temperature. The heater pressure is maintained at 100 kPag by bleed steam. Pump centerline is located 1.0 m above the floor level. Suction line losses is 0.60 m. Determine the minimum height of water level in the heater that must be maintained above the centerline of the pump to avoid cavitation, if the pump to be installed has a required suction head 5.8 m.

! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Consider a two-stage cascade refrigeration cycle with a flash chamber as shown in the figure with refrigerant-134a as the working fluid. The evaporator temperature is −10°C and the condenser pressure is 1600 kPa. The refrigerant leaves the condenser as a saturated liquid and is throttled to a flash chamber operating at 0.45 MPa. Part of the refrigerant evaporates during this flashing process, and this vapor is mixed with the refrigerant leaving the low-pressure compressor. The mixture is then compressed to the condenser pressure by the high-pressure compressor. The liquid in the flash chamber is throttled to the evaporator pressure and cools the refrigerated space as it vaporizes in the evaporator. The mass flow rate of the refrigerant through the low-pressure compressor is 0.11 kg/s. Assume that the refrigerant leaves the evaporator as a saturated vapor…
Power generation using steam is one of the most common method which can be found around the world. In these type of power plants, steam goes through a basic thermodynamic cycle called Rankine cycle which is shown in the following figure. Steam flow Boiler Qin Pump Wout Win Condenser For the proper operation of the cycle, water should be pumped to the boiler using pump which required work input (Wn) to the cycle. Heat energy should be supplied to the boiler (Qin) to generate steam and then high pressure steam is fed to the turbine. By extracting the energy from high pressure steam, turbine is producing work output (Wout)- Because of this, the steam pressure is reduced and low pressure steam is flowing into the condenser. Condenser removes heat energy from steam further (Qout) and steam is converted into liquid water. The liquid water can be pumped into the boiler again and the cycle continues. Performance of a Ranking cycle can be evaluated by using thermal efficiency (neh)which is…
