Suggest a suitable pressure at which dry saturated steam should be supplied to a calorifier (heater) to maintain a chemical process at 140°C, and calculate how much steam would be condensed to provide heat at the rate of 7000 MJ h–1. Allow a temperature difference of 25°C between the steam and the process fluid for effective heat transfer.

Water is the working fluid in a regenerative Rankine cycle with one closed feedwater heater. Steam enters the turbine at 1400 lbf/in.2 and 1000°F and expands to 120 lbf/in.2, where some of the steam is extracted and diverted to the closed feedwater heater. The remaining steam expands through the second-stage turbine to the condenser pressure of 3.5 lbf/in.2 Each turbine stage and the pump have isentropic efficiencies of 85%. Flow through the condenser, closed feedwater heater, and steam generator is...

Saturated water vapor leaves a steam turbine at a flow rate of 1.47 kg/s and a pressure of 0.51 bar. The vapor is to be completely condensed to saturated liquid in a shell-and-tube heat exchanger that uses city water as the cold fluid. The water enters the thin-walled tubes at 17oC and is to leave at 57.6 oC. Assuming an overall heat transfer coefficient of 2000 W/m2K, determine the required heat exchanger surface area and the water flow rate. cp,c...

1) A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume...

Problem 2. A novel gaseous hydrocarbon fuel CxHy is proposed for use in spark-ignition engines. A sample analysis of this fuel revealed that its molecular weight is 140 kg/kmol and its molar H/C ratio is 2. In order to evaluate some of its properties, the fuel was burned with stoichiometric atmospheric air in a constant pressure, steady-flow reactor. The fuel and air entered the reactor at 25 C, and the products of complete combustion were cooled to 25 C. At...

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...
