Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change.(i) Calculate the steam mass flow rate.
The figure belows shows three components of an air-conditioning system, where 105°F and 4.5 lb/s. Refrigerant 134a flows through a throttling valve and a heat exchanger while air flows through a fan and the same heat exchanger. Data for steady-state operation are given on the figure. There is no significant heat transfer between any of the components and the surroundings. Kinetic and potential energy effects are negligible. Modeling air as an ideal gas with constant cp = 0.240 Btu/lb · °R, determine the mass flow rate of the air, in lb/s.

4.13. Consider using the apparatus shown in Fig. 4-1(a), known as the Joule paddle wheel, to determine the specific heat at constant atmospheric pressure. The paddle wheel is driven by a slowly falling weight, and both have a temperature of 14.5°C. As a result of the work done by the 0.427 kg mass that falls 1.00 m, the temperature of 1 kg of water rises 1°C. Calculate cp.

Two separate streams of air and steam flow through a compressor system and a heat exchanger, as shown in the figure. The diagram provides steady state operating data for this system. The transfer of heat with the surroundings can be neglected, as well as the effects of kinetic and potential energy. Air can be considered an ideal gas. Decide:a) The total power generated by both compressors: kW b) The mass flow of water: kg/s
In a quasi-static isobaric expansion, 540 J of work are done by the gas. The gas pressure is 0.90 atm and it was originally at 15.0 L. If the internal energy of the gas increased by 70 J in the expansion, how much heat (in J) does the gas absorb?
A steam catapult is used to assist the acceleration of aircraft from standstill to flight speed in a very short distance. Steam is admitted to the cylinder and steam pressure acts on a piston sliding in a cylinder. The force produced is transmitted to the aircraft by means of a suitable linkage. a) Determine the work done by the steam on the piston if steam is admitted to the cylinder at 20 bar throughout the 25 m stroke. The piston diameter is 500 mm. It may be assumed that the process is reversible. (Ans: W = 9.817 MNm or MJ) m %3D b) In some instances steam is admitted for part of the stroke only and thereafter the fixed mass of steam in the cylinder expands to a reduced pressure. If steam is admitted at 20 bar for 60% of the stroke, the pressure falling linearly to 4 bar over the remainder of the stroke, sketch a diagram of steam pressure against volume and determine the new work done. (Ans: W = 8.24 MJ)
