Step by step solution please I only have 1 attempt thank you. View PoliciesCurrent Attempt in ProgressA 40-lb aluminum bar, initially at Ta = 190°F, is placed in a tank together with 190 lb of liquid water, initially at Tw = 70°F, and allowedto achieve thermal equilibrium. The aluminum bar and water can be modeled as incompressible with specific heats ca = 0.216Btu/lb.°R and Cw = 0.998 Btu/lb.°R, respectively. Consider the aluminum bar and water as the system and ignore heat transferbetween the system and its surroundings.Determine the final temperature Tf, in °F, and the amount of entropy produced within the tank, in Btu/°R.

As an engineer responsible for monitoring works in the area of mechanical systems, you must evaluate the following situation: a large client in the retail area has a refrigeration system where it stores some chilled or frozen products to be sold on the sales floor.Recently, the customer's maintenance department has been questioning the system's performance and requested an evaluation of the system's behavior. You went to the location and requested some information from the maintenance manager about the system, who provided the following data: - The system operates with R-134a refrigerant;- The refrigerated environment is maintained at 0°C and the external environment at 26°C;- The refrigerant flow rate in the system is 0.08 kg/s; In addition to the data provided, you carried out some tests and measured the temperature of the refrigerant fluid at some specific points in the system, such as the compressor inlet and condenser outlet, finding values of 0°C and 26°C respectively.…
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Several forces are acting on a bolt as shown in the diagram below. It is desired to determine the resultant of all of the forces acting on the bolt. The axis of the bolt is at a 45° angle with respect to the x-axis. The line of action of force Pis parallel to the x-axis. The magnitudes of the forces and the angles labeled are as follows: P = 35 N S = 60 N T = 31 N a = 15⁰ Q = 53 N 0 = 25⁰ B = 65° y P T S x
