Water is to be heated from its pipeline temperature of 20°C to 90°C using superheated steam at 450°C and 2.5 MPa in a steady state process to produce 10 kg/s of heated water. In each of the processes below, assume there is ho heat loss.a) The heating is to be done in a mixing tank by direct injection of the steam, all of which condenses. Determine the two inlet mass flows needed to meet the desired hot water flow rate.b) Instead of direct mixing, a heat exchanger will be used in which the water to be heated will flow inside copper tubes and the steam will partially condense on the outside of the tubes.. In this case heat will flow from the steam to the water but the two streams will not be mixed. Calculate the steam flow rate if the steam leaves the heat exchanger at 50 percent quality at 100°C

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part A carnival ride is designed to allow the general public to experience high acceleration motion. The ride rotates about Point O in a horizontal circle such that the rider has a speed vo The rider reclines on a platform A. The platform and the nders (80 kg total) can move up and down the inclined wall as the speed of the ride increases. The coefficient of static friction between the wall and the platform is 0.21 170 5 m Determine the range of values of the constant speed vo for which the platform will remain in the position shown. 9.2 m/s 20 The minimum velocity is m/s, and the maximum velocity is
