Answer:
Hermetic compressors are ideal for small refrigeration systems, where continuous maintenance cannot be ensured.
Explanation:
voltage, current and resistance are the Volt [ V ], Ampere [ A ] and Ohm [ Ω ]
Answer:
The high conversion in a CSTR with not very well mixing occurs mostly if the reactor is micro reactor.
From Literature, mixing due to diffusion depends on concentration or temperature gradients. This is commonly represented in micro reactors.
Also, the residence time distribution (RTD) Analysis provides information on how long the various components of fluid have been in the reactor which leads to more conversion in some cases of fluid reaction.
Answer:
the work required by a reversible pump operating with the same conditions, in kW is 16.39 kW
the isentropic pump efficiency is 78%
Explanation:
Given that;
m = 1.2 kg/sec
T = 50 degree Celsius { Vf = 0.001012 m^3/kg}
P1 = 1.5 Mpa
P2 = 15 Mpa
W-actual = 21 kw
W reversible = m*Vf (p2 - p1)
= 1.2 * 0.001012 * ( 15*10^3 - 1.5*10^3)
= 1.2 * 0.001012 * 13500
= 16.39 kW
the work required by a reversible pump operating with the same conditions, in kW is 16.39 kW
Isentropic Pump efficiency = W-reversible / W-actual
= 16.39 / 21 = 0.78
= 78%
the isentropic pump efficiency is 78%
