The heat exchanger shown in the
figure converts a part of the thermal energy drawn from the
saturated water vapor flowing in a channel into work, transfers the
rest to the lake at 20 ° C temperature and causes the entire vapor
to condense to the saturated liquid. If the power produced by IM is
W = 500kW, what is the mass flux of the steam at least?
IM = ?s? makinesi, heat machine
?ekilde gösterilen ?s? makinesi, bir kanal
içerisinde akan doymu? su buhar?ndan çekti?i
?s?l enerjinin bir k?sm?n? i?e dönü?türmekte,
kalan?n? 20 ? s?cakl???daki göle aktarmakta
ve buhar?n tamam?n?n doymu? s?v?ya
yo?u?mas?na sebep olmaktad?r. IM’nin
üretti?i güç W=500kW ise, buhar?n kütle
debisi en az ne olmal?d?r?
thank you in advance

A shell and tube heat exchanger with one shell pass and one tube pass will be used to condense the steam to saturated liquid, which enters the shell side as a saturated vapor at 400 K. The tube side contains R-134a refrigerant with an inlet temperature of 300 K and a mean velocity of 0.4 m/s. The steam flow rate is 1.5 kg/s. The tubes are made from AISI 302 stainless steel and have a 1" nominal diameter (Di =...

A two-pass shell and tube heat exchanger has an overall conductance l of 450 W/m20 C when used as a condenser for a large air conditioning system. Refrigerant R-134a enters the condenser at 20 kg/ s as a saturated vapor at 70 C and leaves as a saturated liquid. If cooling water enters at a rate of 60 L/s, 10 ° C, determine the outlet temperature of the cooling water and the effective area of the condenser

A shell-and-tube heat exchanger similar to the one shown in the Figure below is used to recover energy from waste water at 40°C to heat fresh water entering at 18°C. The mass flow rate of the waste water is 4 kg/s which is the same as that of the fresh water. Using the data given, calculate: (i) the optimum rate of energy recovery; the required heat transfer area; (iii) the temperature of the fresh water at exit. Shell fluid inlet...
