48. Water is flowing in a smooth pipe of diameter D. A section of this pipe hav- ing a length of L is heated. Water at the inlet to the heated section has a tempera- ture of T7. Water temperature at the exit of the heated section is Tp. The heated section of the pipe wall is maintained at a constant heat flux so that a constant temperature difference of AT, = T, - T exists between the wall and the bulk wa- ter temperature. Show that for turbulent flow in the pipe and a specified heated length and pipe diameter, water temperature at the exit of the heated section is given by: T2 =T, +0.0876 DO.8 AT, - 0.2 Pr0.6 m

For an inlet valve, the mass flow rate through the valve is 0.44 kg/s. The flow coefficient is 0.62 and the cylinder pressure is 105 kPa. Assume intake system pressure and temperature are 180 kPa and 527 K, the specific heat ratio is 1.3 and R =287 J / kg.K. The area of the valve is (SI unit): Select one: a. 2.30*10-3 O b. 3.45*10-2 O c. 1.43*10-3 O d. 1.75*10-3 O e. 0.85*10-2
QUESTION 9 A liquid cooled heat sink for a smartphone is sketched in Figure Q9. It uses water of density p = 997 kg m-3 and kinematic viscosity v = 1.19 x 10-6 m²-s-1 that runs in the x₁ direction through each of the five tubes of constant diameter D₁ = 5 mm and length Lx1 = 20 mm. It is supplied by a U = 0.017 m-s-1 uniform water inflow. Use Blasius' skin friction coefficient Cf = 0.664 / Rex1 0.5 to calculate the total skin friction drag force imparted by the flow on the heat sink walls. Calculate your answer in microNewtons, to one decimal place and enter the numerical value only. 1 microNewton = 10-6 Newtons.

Question B2 - Internal Flow In a large student house in Sheffield, cold water is supplied by the mains water supply at a pressure of 2 bar, gauge, and at a temperature 10°C. A wash basin cold tap is located 3 meters above the mains supply, connected to the mains pipe with a copper pipe of internal diameter 15 mm and length 12 meters. When the tap is opened the flow rate of water out of the tap is 24 litres per minute, creating a Fanning friction factor in the pipe of 0.008. d) If the value were not given, what procedure would be needed to determine the Fanning friction factor?

P.4.7 A heat exchanger is to consist of a number of tubes each 25 mm diameter and 5 m long arranged in parallel. The exchanger is to be used as a cooler with a rating of 4 MW and the temperature rise in the water feed to the tubes is to be 20 deg K. If the pressure drop over the tubes is not to exceed 2 kN/m2, calculate the minimum number of tubes that are required. Assume that the tube walls are smooth and that entrance and exit effects can be neglected. Viscosity of water = 1 mNs/m2. Ans. 116 tubes
