A solar collector design consists of an inner tube enclosed concentrically in an outer tube that is transparent to solar radiation. The tubes are thin walled with inner and outer diameters of 0.10 and 0.15 m, respectively. The annular space between the tubes is completely enclosed and filled with air at atmospheric pressure. Under operating conditions for which the inner and outer tube surface temperatures are 70 and 30°C, respectively, what is the convective heat loss per meter of tube length across the air space?
QUESTION 11 - Steam boiler plant in a petroleum refinery has an overall thermal efficiency on gross C.V . of the fuel of 85 % and an out put of 90720 kg of steam per hour. The steam is produced at a pressure ..
How does phosphorylated PFK-1 activate and deactivate metabolic pathways? How does this relate to the energy state of the cell? What other molecules regulate PFK-1 activity and how?
Assuming RS = 0 and the source voltage to vary between 120 and 75 V, for a load resistance of 1000 Ω, determine the maximum value of the regulator resistor R if it is desired to maintain the load voltage at 60 V. Also find the required power ratin..
Water at 1 bar, 20 °C is heated at const P to produce steam with quality 95%. What is the amount of heat? What is the final state if the amount of heat is 2100 kJ/kg?
Implications of the future of fabrication for international trade, transportation, and logistics
The constant losses from a no-load run as a motor are given to be 220 W, of which 70 W represents friction and wind age losses. Calculate the efficiency of the induction generator.
Calculate the final solution volume and the shaft work in kW that the pump must deliver, assuming that the surface of the stored solution and the pipe outlet are both at 1 atm. Data. PH2O = 1.00 kg/L, Pgly = 1.26 kg/L. (Use to estimate solution de..
An effluent disposal contractor is considering entering the recycled field. At present he incinerates an organic waste containing recoverable solvents and dumps the aqueous based effluent containing acids and metals.
A 100-kW, 250-V shunt generator has an armature-circuit resistance of 0.05 Ω and a field circuit resistance of 60 Ω. With the generator operating at rated voltage,
If the bore of the machine is 42 cm in diameter, its axial length is 28 cm, and each pole subtends an angle of 60°, determine the air-gap flux density. (Note that the number of parallel paths is equal to the number of poles for lap windings.)
How do the ratios determined in parts (a) and (b) compare? What does this tell you about which range may have more areas of practical application?
