Bacteria and viruses are inactivated by temperatures above 141 ∘C in an autoclave. An autoclave contains steam at 1.00 atm and 100 ∘C. At what pressure, in atmospheres, will the temperature of the steam in the autoclave reach 141 ∘C, if n and V do not change?
Calculate the heat that is absorbed/released when 9.00 g of steam condenses to liquid water at 100°C. DHvap(water) = 40.66 kJ/mol.
What is the general principle behind using an autoclave? How does it work? What is the advantage of using an autoclave (generates steam with high pressure and temperature) to sterilize surgical instruments rather than simply boiling them in water? Why must containers of liquid be open prior to autoclaving? What are sterility indicators? Why must they be used?
Subject: Thermodynamics A steam power plant operates on a simple ideal Rankine cycle between the pressure limits of 9 MPa and 10 kPa. The mass flow rate of the steam through the cycle is 60 kg/s. The quality of the steam at the turbine exit is 90 percent. a)What is the turbine inlet temperature in C? b)What is the work output of the turbine in kJ/s?
Steam enters high-pressure turbine of a steam power plant that operates on ideal reheat Rankine cycle at pressure and temperature of 5.5 MPa and 500°C, respectively. The steam leaves the high-pressure turbine as saturated vapor. The steam is then reheated to temperature of 400°C before it expands to a pressure of 7.5 kPa. Answer the following. i) Show the cycle on a T-s diagram with respect to saturation lines. ii) Determine the pressure at which reheating takes place. iii) Determine...
a) A steam power plant operates on an ideal reheat-regenerative Rankine cycle. Steam enters the high-pressure turbine (HPT) at a pressure of 10 MPa and temperature of 550°C. The steam expands through the HPT stage to a pressure of 0.6 MPa. Some of the steam at the end of the expansion process in HPT is extracted for a regeneration process in a closed-type feedwater heater. The steam leaves the heater as a saturated liquid and then is throttled to the...
Steam generated in a Rankine steam power cycle at a pressure of 8 MPa and temperature 600oC is fed to a turbine. Exhaust from the turbine enters a condenser at 100 kPa, where it is condensed to saturated liquid, which is then pumped to the boiler. (a) (20 pts.) What is the thermal efficiency η of an ideal Rankine cycle operating at these conditions? (b) (5 pts.) If the net power production of the cycle is 80,000 kW, what is...
(2) Steam generated in a Rankine steam power cycle at a pressure of 8 MPa and temperature 600°C is fed to a turbine.

Question 5 1.5/3 points In a Rankine cycle, steam leaves the boiler and enters the ideal turbine at 6.9 MPala) as a saturated vapor. Condenser pressure is 6.9 kPaſa). The specific enthalpy of the subcooled condensate/feedwater at the discharge of the feedwater pump (h) is 166.36 kJ/kg. Identify the specific enthalpy (in kJ/kg) of the steam entering the turbine. 166.36 Calculate the quality (in %) of steam-water mixture leaving the turbine. Calculate the specific enthalpy (in kJ/kg) of the steam...
