(Problem) An air-standard Otto cycle has a compression ratio of 9. At the beginning of compression, p1 = 95 kPa and T1 = 37°C. The mass of air is 3 g, and the maximum temperature in the cycle is 1020 K. Determine (a) the heat rejection, in kJ. (b) the net work, in kJ. (c) the thermal efficiency. (d) the mean effective pressure, in kPa.

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

Required information Problem 09.052 - Ideal Diesel Cycle with Variable Specific Heats - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS An air-standard Diesel cycle has a compression ratio of 16 and a cutoff ratio of 2. At the beginning of the compression process, air is at 103 kPa and 27°C. Account for the variation of specific heats with temperature. The gas constant of air is R= 0.287 kJ/kg-K. Problem 09.052.b - Thermal Efficiency in Variable Heat Capacity Diesel Cycle Determine the thermal efficiency. (You must provide an answer before moving on to the next part.) The thermal efficiency is 59.38 %.

A compression ratio of 18:1 is utilized in the functioning of an air-standard dual cycle. The temperature is 298 degrees Kelvin, there is 1 bar of pressure, and the volume is 4 liters. The total amount of heat that is added is 6.3 kJ, of which only 30% is added while maintaining a constant volume and the remaining 60% is added while maintaining a constant pressure. What is the temperature after the constant pressure heat addition process in Kelvin?
