(a) Liquid water in a tank can be converted into ice just by evacuating the air from the tank without using heat exchanger. Explain the process and how the device works and the process can be made more efficient. (b) If you have two pots with the same volume but different shapes, one is tall and narrow the other is wide and short, compare and explain about the boiling temperature of the two cases. Discuss the reason why the required temperature for the two cases are different or same on the basis of your answer.

7. A pan made of stainless steel contains water at atmospheric pressure. The pan diameter is 25 cm and its surface is mechanically polished. The pan is now heated while its surface is maintained at 116 C. Find the surface heat flux, the boil off (evaporation) rate, and the peak heat flux
An evaporator is concentrating F kg/hr at 311K of a 20 wt % solution of NaOH to 50%. The saturated steam used for heating is at 399.3 K. The pressure in the vapor space of the evaporator is 13.3 kPa abs. The overall coefficient is 1420 W/. K and the area is 86.4 square meters. Calculate the feed rate F of the evaporator.

Q) Calculate the total amount of rejected heat that will be required to convert 0.5 Kg of steam at (150 ° C ) into ice at (-30 ° C). Take: Cice = Cwater Csteam = Cwater
A steam trap is a device to purge steam condensate from a system without venting uncondensed steam. In one of the crudest trap types, the condensate collects and raises a float attached to a drain plug. Whenthe float reaches a certain level, it “pulls the plug,” opening the drain valve and allowing the liquid to discharge. The float then drops down to its original position and the valve closes, preventing uncondensed steam from escaping.(a) Suppose saturated steam at 25 bar is used to heat 100 kg/min of an oil from 135°C to 185°C. Heat must be transferred to the oil at a rate of 1:00 x 10 4 kJ/min to accomplish this task. The steam condenses on the exterior of a bundle of tubes through which the oil is flowing. Condensate collectsin the bottom of the exchanger and exits through a steam trap set to discharge when 1200 g of liquid is collected. How often does the trap discharge?(b) Especially when periodic maintenance checks are not performed, steam traps often fail to close completely…
Please show the coimplete solution. (Example: Conversion of Units) In an ammonia condensing machine (Compressor Plus Condenser) the water used for condensing is 55°F and the evaporator is at 15°F. Calculate the ideal COP.
A feed of 4535 kg/h of a 2.0-wt % salt solution at 311K enters continuously in a single effect evaporator and is being concentrated to 3.0 %. The evaporation is at atmospheric pressure and the area of the evaporator is 69.7 m2. Saturated steam at 383.2 K is supplied for the heating. Since the solution is dilute, it can be assumed to have the same boiling point of water. The heat capacity of the feed can be taken as cP = 4.10 kJ/kg-K. Calculate the amounts of vapor and liquid product and the overall heat transfer coefficient U. Solution:1. Use the Solute Balance to calculate for the liquid product L 2. Use the overall mass balance to calculate for the vapor product V 3. Calculate for the enthalpy of the feed hF and the enthalpy of the liquid product hL using the h = CPdT.

Pre-lab 8: Cold Engine The experimental setup for this week's lab consists of a syringe connected to a metal can (reservoir), a cold bath (water - ice mixture) and a "hot" bath (water at room temperature). A schematics of the syringe - reservoir system is shown below. Plunger of mass m Filled with gas (air) Syringe of volume Vcor VH - Volume Vo includes tube + Metal can -Metal can submerged in water of temperature Тс or TH. Tube Stopper Figure 1: Schematic of the syringe - reservoir system. The syringe is essentially a glass cylinder fitted with a movable piston (plunger). The markings on the syringe indicate the volume of gas in the syringe, but do not include the additional, unknown volume, Vo, in the gas can and tubing.
