36. In a car tire are 9.0 dm³ air at 12 °C under a inflation pressure of 2.2 bar. During a long journey, the air inside the tire warms up to 76 °C as a result of flexing and sunlight. The tire extends insofar that the new air volume is 9.4 dm. Which inflation pressure prevails in the tire? [pressure 2.75 bar]

Air at a temperature of 95 F and a velocity of 20 ft/s flows over a hot flat plate, maintained at 482 F. Find the rate of heat transfer form this 1ft by 1 ft square plate. [Ans. ~ 423 Btu/hr].
Q3 please thanks
The gravitational constant g is 9.807 m/s2 at sea level, but it decreases as you go up in elevation. A useful equation for this decrease in g is g = a – bz, where z is the elevation above sea level, a = 9.807 m/s2, and b = 3.32 × 10–6 1/s2. An astronaut “weighs” 80.0 kg at sea level. [Technically this means that his/her mass is 80.0 kg.] Calculate this person’s weight in N while floating around in the International Space Station (z = 354 km). If the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel immediately after the satellite stopped moving? In light of your answer, explain why astronauts on the Space Station feel “weightless.”

[Technically this means that his/her mass is 80.0 kg.] Calculate this person's weight in N while floating around in the International Space Station (z=325 km). If the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel Immediately after the satellite stopped moving? The person's weight in N while floating around in the International Space Station Is The astronaut feels a gravitational acceleration of m/s² N.

1 The following observations are recorded during a test on a four-stroke petro engine, F.C = 25cc of fuel in 10 sec, speed of the engine is 2600 rpm, B.P = 22 kW, Qair 0.00134 m, piston diameter 90 mm, density of the fuel = 0.85gm/cc , compression ratio = 7.5, CV of fuel = 42000KJ/Kg, room temperature = 24 °C %3D = 140mm, stroke length = %3D %3D %3D 2 A six-cylinder 4-stroke cycle petrol engine is to be designed to develop 250 kW of (b.p) at 2200 rpm the stroke / bore ratio is to be 1.3:1. Assuming nm =80% and an indicated mean effective pressure of 9.5 bar, determine the required bore and stroke. If the compression ratio of the engine is to be 7.5 to 1, determine consumption of petrol in kg/h and in kg/bp.hr. Take the ratio of the indicated thermal efficiency of the engine to that of the constant volume air standard cycle as 0.65 and the calorific value of the petrol as; 44770KJ/kg.
