Strengthening of Alloys

Strengthening of the alloys is required as metals become weak due to various lattice defects, metal bonding phenomena. The strength of the metals is not enough for any mechanical work. The internal dislocations of any metals arise due to forming processes. Due to the movement of these dislocations, the metals are plastically deformed.

A heat pump with refrigerant-134a (R-134a) as the working fluid is used to keep a space at 21 °C by absorbing heat from geothermal water that enters the evaporator at Ti,water = 60 °C at a rate of 0.067 kg/s and leaves at To,water = 40 °C. The specific heat of liquid water is 4.18 kJ/(kg∙K). Refrigerant enters the evaporator at TR-134a = 10 °C with a quality of x = 12 % and leaves at the same pressure as saturated R-134a vapor at the same temperature. The compressor consumes 1.4 kW of power. 1)Determine the mass flow rate (in kg/s) of the refrigerant. 2)Determine the rate of heat (in kW) supplied to the space. 2)Determine the COP of the heat pump. 4)Determine the ideal minimum power input (in kW) to the compressor for the same rate of heat supply
ercise 6 6.1 A surface condenser is fitted with separate air and condensate outlets. A portion of the cooling surface is screened from the incoming steam and the air is passes over these screened tubes to the air extraction and becomes cooled below the condensate temperature. The condenser receives 20 000kg/hr of dry saturated steam at 36.2°C. At the condensate outlet the temperature is 34.6°C TK and at the air extraction the temperature is 29°C. The volume of air and vapour leaving the condenser is 3.8m3/min. Assume constant pressure throughout the condenser, calculate: 6.1.1 the mass of air removed per 10 000kg of steam (2.63kg); 6.1.2 the mass of steam condensed in the air cooler per minute (0.5kg/min)%3B 6.1.3 the heat rejected to the cooling water (13451kW).
I need help on the following question: The vapour compression cycle (picture provided), utilises the refrigerant R134a flowing at 0.05 kg s-1. Assuming that the compression is adiabatic and reversible. If the actual input power to the compressor is 2 kW, then: 1. You need to determine the theoretical input power to the compressor and the heat transfer (Φ) to theevaporator. Take the enthalpies h1, h2, and h3 to be 238.41, 263.68 and 81.5 kJ kg-1 (use the 'NH3 Refrigeration Table' where you can find online). 2. You need to determine the coefficient of performance based on your answer to the previous question (1). 3. You need to determine the compressors mechanical efficiency.
Please show step by step solution not just answers and how each value is derived dont just mention from a table becuase i cant fnd it, if mentioned please display it.
The evaporator (a heat exchanger) in an A/C unit has R-410A entering at -20 °C and a quality of 30% and leaves at the same temperature and a quality of 100%. The COP of the air conditioner is known to be 1.3 and the mass flow rate is given as 0.013 kg/s. Find the power input to the cycle. (Note that, here, the evaporator is the part of the A/C unit that accepts [i.e., withdraws] heat from the room maintained at a cold temperature)
