A 10 kg mass placed on an infinitely long horizontal massless flat platform is to be supported by a steady vertical water jet as shown in the figure. The diameter of the jet is 5 cm. What minimum average velocity is required to hold the mass in place? Assume 𝜌௪௧ൌ1000 kg/mଷ, 𝑔ൌ10 ୫ ୱమ and 𝜋ൌ3.14 . Neglect friction. (Round off to two decimal places)
Answer: 6.95 to 7.20
