Sunland University recently signed a contract with the bargaining unit that represents full-time professors. The contract agreement starts on April 1, 2022, the start of the university's fiscal year. The following excerpt outlines the portion of the signed agreement that relates to sabbaticals: "Professors may apply for a one-year sabbatical leave after seven continuous years of employment and must outline how their sabbatical plans will benefit the university." After completing the required amount of time, any professor may apply for the leave. The contract notes particular types of activities that the sabbatical is intended to promote, including formal research, continued professional development, and independent study and research. Professors are left to make their own choices regarding which of these activities to pursue while on sabbatical leave. As part of their agreement, they must continue to work for the university one year after their sabbatical or reimburse it for funds they receive while on leave. The agreement states that professors receive 80% of their salary while on sabbatical leave. Professors may delay, or be asked to delay, their application for sabbatical, in which case they will receive 85% of their salary while on leave. The issue of sabbaticals had long been a point of contention with faculty at Sunland University, and they fought vehemently for the right to this paid leave, which had not previously been in their collective agreement. The university is phasing in the unfunded sabbatical plan gradually, which means that the first professors will be eligible to apply for their sabbaticals in seven years. The controller has put together the following numbers of professors in each salary group: Professors with salaries averaging $59,030 55 Professors with salaries averaging $68,530 45 Professors with salaries averaging $108,800 10 The union agreement calls for a salary increase of 2% per year in each of the next seven years. This is consistent with past union agreements for this bargaining unit. Five of the professors with salaries averaging $108,800 are scheduled to retire in four years. The university expects to keep a similar composition of salaried professors in the future. Assume a discount rate of 6%. Assume that Sunland University is a private university that applies ASPE. (b) Your answer is partially correct. Prepare any entries that are required at the March 31, 2023 fiscal year end assuming sabbaticals will be granted automatically with no restrictions on the professors' activities during the year. Use a financial calculator or Excel function for your calculations.

P4.53 Connie Chemist has developed a new catalyst for making acetaldehyde from ethanol and air. Besides the desired reaction, some ethanol is oxidized completely to CO2 and H2O. Connie analyzed a laboratory scale continuous-flow reactor. The feed to the reactor is set at 5.7 moles ethanol per mole oxygen. Under these conditions, the single-pass conversion of ethanol is 25%, with selectivity to acetaldehyde of 0.92. Sketch a block flow diagram showing how you would design this process at a large scale, to produce 1200 kgmol/h acetaldehyde. Include recycle and purge streams as you see fit. Assume that nitrogen, oxygen, and carbon dioxide cannot be economically separated, and that ethanol, water, and acetaldehyde can all be readily separated from each other. Complete a DOF analysis of the process. Calculate all flows.
