A stream of pure cyclopentane vapor flowing at a rate of 1550 L/s at 150 ºC and 1 atm of pressure enters a cooler, which is operating at 1 atm. The cooler functions as a flash separator (one liquid outlet stream, one vapor outlet stream) with 75% of the feed being condensed and exiting the cooler at 1 atm. The liquid stream exiting the cooler is in equilibrium with the exiting vapor. Use a molar flow and enthalpy summary table to help organize your work.

How to estimate the size of a heat exchanger that is heat water up from 20C-120C.
5,000,000 g of H2O needed (5000 L H2O)
I have calculated that Q = 2.093*10^9 J
Please tell me how to determine what the size will be and how much power will be required for this heat exchanger to operate. please explain each step and equation

The reversible reaction aA « bB+cC is performed in a membrane reactor – C diffuses through the membrane. If the feed is pure A at 298K and 1.02 atm and the reactor volume is 500L, find the molar rates, Fj, the concentrations, Cj, and the conversion of A as a function of reactor volume. What is the conversion of A for this reactor? Data: k1, forward rate constant is 1 (min-1); Kc (equilibrium constant) = 2.198 x 104 mol/m3, kc (mass transfer coefficient) = 4.2 (1/min), FAo=10 mol/min; a=1, b=1,c=1

A window-mounted air conditioner supplies 29 m3/min
of air at 15°C, 1 bar to a room. Air returns from the room to the
evaporator of the unit at 22°C. The air conditioner operates at
steady state on a vapor-compression refrigeration cycle with
Refrigerant 22 entering the compressor at 4 bar, 10°C. Saturated
liquid refrigerant at 9 bar leaves the condenser. The compressor
has an isentropic efficiency of 70%, and refrigerant exits the
compressor at 9 bar.
Determine:
(a) the compressor power, in kW.
(b) the refrigeration capacity, in tons.
(c) the coefficient of performance.

Refrigerant 134a is the working fluid in a vapor-compression
heat pump that provides 35 kW to heat a dwelling on a day when the
outside temperature is below freezing. Saturated vapor enters the
compressor at 2.1 bar, and saturated liquid exits the condenser,
which operates at 8 bar.
Determine for an isentropic compressor efficiency of 75%:
(a) the refrigerant mass flow rate, in kg/s.
(b) the magnitude of the compressor power, in kW.
(c) the coefficient of performance.
