(a)
Interpretation:
The rate at which heat is transferred from the condenser is to be calculated.
Concept introduction:
The rate of heat transfer is calculated as:
For an adiabatic system, the heat lost by one component in the system is the heat gained by another component in that system. Thus,
(b)
Interpretation:
The state of the product stream is to be determined if the heat is transferred at the lower rate than that calculated in part (a).
Concept introduction:
Removal of heat from any vapor at its normal boiling point leads to the condensation of the vapor to liquid phase until all the vapor is condensed and further removal of heat leads to the cooling of the liquid. If less heat is removed from the vapor, then partial condensation happens, and vapor and liquid coexist at its normal boiling point.
(c)
Interpretation:
The state of the product stream is to be determined if the heat is transferred at the higher rate than that calculated in part (a). Also, a phase diagram is to be drawn.

Now, there is an isobutane tank that initially contains 15 L of liquid isobutane, at an ambient temperature of 25 ° C. If a leak occurs in the tank connection tube, determine the temperature of the isobutane when the pressure in the tank drops to 1atm. Also determine the total amount of heat transfer from the environment to the tank required to evaporate all the isobutane in the tankarrow_forward
- A 3.1 kg mass of saturated liquid-vapor mixture of water is contained within a closed system in a vertically arranged piston-cylinder device at a pressure of P1. Initially, 1.1067 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches P2. Heat transfer continues until the total volume increases by 19 percent.

- A steady-state process to recover crystalline potassium chromate (K,CrOz) from an aqueous solution of this salt is required. Four thousand kilograms per hour of a solution that is one-third K,CrO, by mass is joined by a recycle stream containing 36.4% K2CrO7, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K,CrO; this stream is fed into a crystallizer in which it is cooled (causing crystals of K,CrO, to come out of solution) and then filtered. The filter cake consists of K,CrO, crystals and a solution that contains 36.4% K,CrO, by mass; the crystals account for 95% of the total mass of the filter cake.

Also, hypergolics do not pose the storage problems of cryogenic propellants (e.g., liquid oxygen and hydrogen) as they remain liquid at normal temperatures. This technology was used on the Apollo 11 Mission 40+ years ago. As part of the testing for a new thruster design, amounts of unsymmetrical dimethyl hydrazine, or UDMH [(CH3)2N-NH2; MW=60.1 g/mol] were reacted with dinitrogen tetroxide [N2O4; MW=92.1 g/mol].
