by mistake, i have taken property at 335 instead of 235. now i
have corrected mistake and upload steam property also at the 235 C.
feel free if u have any doubt regarding same.
A Carnot's engine has a low temperature reservoir at 7 °C with
efficiency of 40%. It is desired to increase the efficiency to 50%.
By how many degrees should the temperature of the high temperature
reservoir be increased?
A binary geothermal power plant uses geothermal water at 160°C
as the heat source. The plant operates on the simple Rankine cycle
with isobutane as the working fluid. Heat is transferred to the
cycle by a heat exchanger in which geothermal liquid water enters
at 160°C at a rate of 555.9 kg/s and leaves at 90°C. Isobutane
enters the turbine at 3.25 MPa and 147°C and leaves at 79.5°C and
410 kPa. Isobutane is condensed in an air-cooled condenser and...
A refrigerator with R-410a as the working fluid has a minimum
temperature of −10°C and a maximum pressure of 1 MPa. Assuming an
ideal refrigeration cycle, find the specific heat transfer FROM the
cold space, the specific heat transfer TO the hot space, and the
coefficient of performance. Will this refrigeration cycle work in
an ordinary kitchen?

A water has a temperature of 10o C and pH = 8. What
should be the C.t value for 3-log Giardia removal using (a)
chlorine, (b) chloramine. Assume a chlorine residual of 1.0 mg/L is
required. If the chlorine dosage required to achieve this residual
is 1.6 mg/L, what is the chlorine requirement in lbs/d for a 2 mgd
water plant.
