Question 1Two gas tanks are connected by a cylindrical tube, of length 20 cm and radius 1.5mm. As shown in the diagram, a valve, which allows ideal gases to be exchangedbetween the two tanks, is positioned between the tanks and is initially closed. Bothgases are initially at 25 °C.0.002 m³Valve0.001 m³4/51/5101 kPa10 kPaThe valve is now opened and gas is allowed to flow in the tube at constanttemperature. What is the pressure in the 0.002 m³ tank when the valve is left openand equilibrium is reached? Give your answer to two significant figures and in kPa.

A depressurization blower test was conducted in a 3-floor rectangular building with a height of 10 m and a total floor area of 100 m^2. The results of the blower door tests were expressed by the power-law equation with the flow exponent of 0.65 and the flow coefficient of 850 m3/hr. Determine ACH50, ELA4 (C=1, the discharge coefficient). Assume the air density as 1.2 kg/m^3.
Superheated steam is contained in a 4.25-m rigid- tank at a constant temperature T = 350 °C. The initial pressure inside the tank is 3500 kPa. A valve is opened, and 0.75 kg/min of steam allowed to escape from the tank. How long it takes (in minutes) for pressure inside the tank to reach to 600 kPa?

Design a hydrocooling unit that can cool fruits and vegetables from 30 to 5 °C at a rate of 20,000 kg/h under the following conditions:The unit will be of the flooded type, which will cool the products when they are transported in the channel filled with water. Products will be dropped into the water filled chute at one end and collected at the other end. The channel can have a width of up to 3 m and a height of up to 90 cm. The water will circulate and be cooled by the evaporator section of a refrigeration system. The temperature of the refrigerant inside the coils will be 2°C, and the temperature of the water must not fall below 1.5°C and must not exceed 7°C.Assuming reasonable values for the average density, specific heat, and porosity of the product (the fraction of the volume of air in a box), recommend reasonable values for a) the velocity of the water through the channel and b) the flow rate refrigeration system cooling (QL). For the calculation of the reasonable values…
