Heat and Mass Transfer

$2000\text{ kg/h}$ of milk is heated from $20.0^\circ\text{C}$ to $80.0^\circ\text{C}$ by condensing steam in a jacketed heat exchanger. The specific heat of milk is $C_p = 3.90\text{ kJ/(kg}\cdot\text{K)}$ and the latent heat of condensation of steam is $\lambda_s = 2250\text{ kJ/kg}$. Neglecting heat losses, the steam consumption rate in $\text{kg/h}$ is ________ (answer in integer).
