12. Imagine a solar collector for hot tap water in a hot climate. De outdoor temperature is 22 degree Celsius. De tank of the solar collector is placed outside, and the cold water temperature to the collector is 20 degree Celsius. De water flow rate through the collector is 45 liter/hour. De collector is 2 [m2] and the average solar radiation in the time period considered is 1000 [W/m2]. What is the temperature of the hot water to the tank? The efficiency of the collector can be assumed to be 0.7 (we neglect the dependency to the water temperature) (multiple choice, one answer) 34 [OC] 47 [OC] 54 [OC] 67 [OC] 74 [OC]

An ideal gas flows through a horizontal tube at steady state. No heat is added, and no shaft work is done. The cross-sectional area of the tube changes with length and this causes the velocity to change. (a) Derive an equation relating the temperature to the velocity of the gas.(b) If nitrogen at 150 [°C] flows past one section of the tube at the velocity of 2.5 [m/s], what is the temperature at another section where its velocity is 50 [m/s]?

Air is allowed to flow from a reservoir with temperature of 21∘C and with pressure of 5[MPa]through a tube. It was measured that air mass flow rate is 1[kg/sec]. At some point on the tubestatic pressure was measured to be 3[MPa]. Assume that process is isentropic and neglect thevelocity at the reservoir, calculate the Mach number, velocity, and the cross-sectional area at thatpoint where the static pressure was measured. Assume that the ratio of specific heat isk=Cp/Cv=1.4.
