True Story! The 1998-1999 Mars Climate Orbiter mission was declared a total loss in1999 as there was a unit conversion mismatch error between Lockheed Martin and NASA. Themismatch was in the thruster force units. NASA used the SI system which called forNewton-Seconds (4.45 times as large) of thrust and Lockheed Martin used Pound-Force Seconds.Calculations placed the Orbiter at 68 miles from the surface as it went into orbit, but it waswithin 57 km of the surface after the breaking maneuver. Any distance from the surface lessthan 50 miles would have caused the Orbiter to crash.a. What was the actual distance of the Orbiter from the surface in miles?b. In percentage, how far off from the calculated 68 miles was the Orbiter?

Problem 3: Insulation To=1 Toowwww Steam Tx2 T₂ T3 www www R₁ R₁ R₂ www.T R₂ Steam at T1 = 320 °C flows in a cast iron pipe (k= 80 W/m. °C) whose inner and outer diameters are 5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation. The determination is based on a unit length of the pipe (L = 1 m). Assumptions 1. Heat transfer is one-dimensional since there is no indication of any change with time. 2. Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no variation in the axial direction. 3. Thermal conductivities are constant. 4. The thermal contact resistant at the interface is…
