TER 201 Termodinamik Uygulamalar 1. Bir piston-silindir cihazında başlangıçta 1.0 MPa ve 400°C'da 0.3 kg buhar bulunmaktadır. Piston durdurucularının pozisyonu başlangıç hacminin %60'ına karşılık gelmektedir. Buhar daha sonra soğutulmaktadır. Sıkıştırma işini son hal (a) 1.0 MPa ve 250°C, ve (b) 500 kPa için hesaplayınız. Ayrıca (b) halindeki son sıcaklığı saptayınız. 2. Bir piston-silindir mekanizması başlangıçta 250 kPa'da 0.8 m³ doymuş buhar içermektedir. Bu durumda; piston, silindir içindeki piston durdurucularının üzerine dayanmakta ve pistonun sahip olduğu kütle, pistonun ancak 300 kPa basınç etkisiyle hareket etmesine izin vermektedir. Silindir içindeki buharın hacmi iki katına çıkana dek yavaşça ısı aktarımı yapılmaktadır. Bir P-v diyagramında doyma eğrileriyle birlikte işlemi gösteriniz ve (a) son sıcaklığı, (b) işlem sırasında yapılan işi, ve (c) toplam ısı aktarımını hesaplayınız. 3. Sürtünmesiz bir piston-silindir cihazında 100 kPa ve 300 K'de 2 kg Azot bulunmaktadır. Azot, $PV^k$=sabit bağıntısına göre son sıcaklığı 360 K oluncaya kadar yavaşça sıkıştırılmaktadır. Bu işlem sırasındaki iş girişini hesaplayınız. 4. İyi izole edilmiş rijit bir tankda 100 kPa basınçta 5 kg doymuş sıvı-buhar karışımı su bulunmaktadır. Başlangıçta, toplam kütlenin ¼'ü sıvı fazdadır. Tank içindeki rezistans 110 V bir kaynağa bağlanıp 8A akım geçirilmektedir. Tank içindeki sıvının tamamının buharlaşması için ne kadar zaman gerektiğini hesaplayınız. İşlemi bir T-v diyagramında doymuş sıvı ve buhar eğrileri ile birlikte gösteriniz. 5. A ve B tankları bir bölmeyle ayrılmışlardır. A tankında başlangıçta 1 MPa ve 300°C'da 2 kg buhar bulunmaktadır. B tankında ise 150°C'da %50 kuruluk derecesinde 3 kg doymuş sıvı-buhar karışımı bulunmaktadır. Bölme kaldırıldığında iki kısmın mekanik ve ısıl denge tesis edilinceye kadar karışmalarına izin verilmektedir. Son halde basınç 300 kPa ise (a) son halde buharın sıcaklığını ve doymuş halde ise kuruluk derecesini (b) tanklardan kaybedilen ısı miktarını saptayınız.

Problem 3 (8 points): New Orleans Outpatient Surgery Center is developing an operating budget for the year ending June 30, 2025. The Center expects to perform 80 surgical procedures each month and also anticipates an increase to 86 procedures per month starting on March 1, 2025. New Orleans' average charge (price, revenue) per surgical procedure is $2,500 and they expect an increase of 3% starting January 1, 2025. The cost of disposable surgical supplies is $300 per surgical procedure. New Orleans Outpatient Surgery Center also contracts with orthopedic surgeons at a fee (expense) of $1,500 per surgical procedure and they have been informed this fee will increase by 5.38% on February 1,2025 . The monthly salaries for the Center's receptionist, bookkeeper, and two surgical nurses total $10,500. The staff will receive a raise of 2.8% on October 1, 2024. The Center's occupancy costs, which include space rental, insurance, and all utilities, are $8,200 per month. Average monthly communication costs are $1,200. Office and operating room equipment was installed at a cost of $240,000. The equipment is expected to have a five-year life and has no salvage value. Prepare New Orleans Outpatient Surgery Center's Operating Budget for the year ending June 30, 2025. Your budget should also include a monthly budget for each of the twelve months in the fiscal year. Lastly, the budget should show a cumulative budget total for the entire fiscal year.
