A venturi tube is used to determine the airspeed at the throat/test section. During the test, a raise of 4.8 inches of water was recorded in the instrument. Determine the velocity of the at the (a) smallest and (b) largest section, when the ratio of the area between the largest and smallest section is 75:30. Assume incompressible flow and standard sea-level conditions. the answer should be v1 = 63.1962 ft/s and v2 = 157.9905 ft/s

This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. From measurements of a photograph, it has been found that as the stream of water shown left the nozzle at A, it had a radius of curvature of 17 m.   Determine the radius of curvature of the stream as it reaches its maximum height at B.    The radius of curvature of the stream is m.?   Note: please show step by step solution. Hence, double check the solution. For correction purposes!. I require  handwritten working out please!. Kindly, please meticulously, check the image for conceptual understanding and for extra information purposes!. Also on occasions, I receive wrong answers!!. Please go through the question and working out step by step when you finish them. Appreciate your time!.

The jet car is originally traveling at a velocity of 10 m/s when it is subjected to the acceleration shown. When t = 0, s = 0. Suppose that a1 = 6 m/s? , a2 = -4 m/s? , and t" = 13 s. (Figure 1) Part A Determine the car's maximum velocity. Express your answer to three significant figures and include the appropriate units. μΑ ? Umax = Value Units Figure 1 of 1 a (m/s³) Submit Request Answer Part B Determine the time t' when the car stops. Express your answer to three significant figures and include the appropriate units. t (s) µA ? az t' = Value Units
