A) Liquid sodium flowing a 100 kg/s, enters a heat exchanger at 450 C and exits at 350 C. The specific heat of sodium is 1.25 kJ/kg.K. Water enters at 5000 kPa and 20 C.
Determine the minimum mass flow rate (kg/s) of the water so that the water not completley vaporize. Neglect the pressure drop through the exchanger and assume a saturated vapor state for the exiting steam to obtain the maximum allowable exiting enthlapy. Also, calculate the rate of heat transfer (kW) to the water.
b) A family has a natural hot spring on their property. They wish to use the hot groundwater to power heat engine and generate electricity. If the groundwater is 95 C and a mass flow rate of 0.2 kg/s is possible, estimate the maximum power output (kW). you may assume a constant specific heat for water during the process.
What is the inner tube surface temperature at the outlet, where fully developed conditions may be assumed?
Determine a) the volume of the tank,b)the final temperature and pressure, and c) the internal energychange of the water.
the 60-kg uniform rectangular plate rotates in a vertical plane around point a. force p is being applied to point c on
what is the cw when i10 per year of 1500 per year starting in year one and continuing forever and 10000 in year five
A 90-N force is applied to the control rod AB as shown. Knowing that the length of the rod is 225 mm, determine the moment of the force about point B by resolving the force into horizontal and vertical components.
a rigid tank is filled with refrigerant r-134a at 310 k. an electric current of 0.2 amps over 220 volts is passed
some bacteria are propelled by biological motors that spin hair-like flagella. a typical bacterial motor turning at a
assume that a seismically excited system is accurately modeled by a mass attached to the ground by a spring and a
assuming that steam can be treated as an ideal gas what would the specific volume of steam be at 600deg f and 120 psia
During the process, the pressure and specific volume are related by pv = constant. For the refrigerant, determine the work and heat transfer per unit mass, each in KJ/kg.
a scuba divers 2 cubic foot air tank is to be filled with air from a compressed air line at 120 psia and 100 degrees f.
two jets of air of equal mass flow rate mix thoroughly before entering a large reservoir. one jet is at 400 k and 100
